Legrand is a new employee, a new hire. That is why he did not know me until recently. He applied for a consulting position, had good credentials, and we hired him recently. Now he knows me; before, he used my results in the Wenocur-Dudley and Wenocur-Salant work as well as the other statistics. So he once knew of me, now he has met me. Clear? Hope so. Our website is in its infancy, and we have put it to sleep for a while, until we can make it better. [[User:RDSW|RDSW]] ([[User talk:RDSW|talk]]) 18:20, 8 January 2008 (UTC) |

:So, the extreme similarity in names between your employee Alfred Legrand and your brother Alfred Small is just that, a coincidence? And how is it that new hire Legrand was so interested in your family that he created the [[Alfred Small]] article? —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 18:34, 8 January 2008 (UTC) |

:Probably I will, eventually. I want to take the time to formulate my opinion carefully. Btw, you should be aware of [[WP:CANVAS]] — going around to individual talk pages asking people to contribute to an AfD, unless they've contributed significantly to the article (and I don't think my categorization counts), can be seen as bad form. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 03:04, 6 January 2008 (UTC) |

:*[[User_talk:Alfred_Legrand]] looks, to me, a lot like [[User_talk:MathStatWoman]]. MathStatWoman was caught out by Checkuser and may have gotten wiser.

::*The "Hello." at Legrand's user talk matches the "Goodbye." at MathStatWoman's user page. And it is suggestive of something that one of [[User:Alfred Legrand|Alfred Legrand]]'s creations was [[Alfred Small]], with such a similar name. But I'm not sure I see what you mean about the talk page similarity: you mean the fact that they both leave their replies elsewhere?

:::I'm kicking myself for not having noticed the Small/Legrand bit.

== Erdős number of Jonathan Harel == |
|||
Dear Professor Eppstein, |
|||
I noticed you removed Jonathan Harel from the [[List of people by Erdős number]] and |
|||
that The Erdos number project lists a Jonathan Harel with Erdős number two (via Robert J. McEliece). scholar.google.com did in fact find something with those two authors ('Proceedings of the International Symposium on Information'). Could you elaborate on your (the) criterion for including people on the [[List of people by Erdős number]]? |
|||
Thanks. [[User:Lklundin|Lklundin]] ([[User talk:Lklundin|talk]]) 10:38, 14 January 2008 (UTC) |
|||
:Basically the same as the [[Wikipedia:Red link|criteria for making redlinks anywhere in Wikipedia]]: only do it if it seems likely that the subject of the link is notable enough to support an actual article, and that the only reason the link is red instead of blue is that nobody has yet taken the trouble to make the article. That is, we're not listing everyone with Erdos number 2 (that would be unmanageably large, and redundant with the Erdos number project's list) but only the subset of those people who are notable enough to have Wikipedia articles. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 16:42, 14 January 2008 (UTC) |
|||
::OK, you made a convincing argument that the redlink should be removed. And you have a good point that listing all known people with an Erdős number of two but make for a rather large page. I brought up the issue initially because I am considering to try and complete the list of people with an Erdős number of one - and because the bottom of the page has the ''expand list'' tag - perhaps the use of this tag should be reconsidered for this particular list.

== is it vandalism? == |

User [[User:David Eppstein|David Eppstein]] deleted a link and wrote that big article printed in well-known scientific journal by Springer is "non-notable paper" - is it vandalism? See: [[Talk:Graph isomorphism#The_absurd_reason_that_looks_like_vandalism_against_NPOV]]--[[User:Tim32|Tim32]] ([[User talk:Tim32|talk]]) 17:56, 18 January 2008 (UTC) |
|||
:No, it's merely a content dispute. See [[Wikipedia:Vandalism]] for a description of what vandalism really is. Note also that accusations of vandalism for good-faith edits such as this may be considered as a violation of policies and guidelines on Wikipedia to [[WP:CIVIL|be civil]], [[WP:AGF|assume good faith]], and [[WP:NPA|avoid personal attacks]]. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 18:09, 18 January 2008 (UTC) |

|||
:[[User:Tim32|Tim32]]'s comment in [[Talk:Graph isomorphism]], where he used the term 'Vandalism against NPOV' is contrary to the current understanding of 'vandalism.' Vandalism is a deliberate attempt to make the encyclopedia worse, which does not seem to be the case here. Use [[Wikipedia:Dispute resolution]] if you can't get any satisfaction in a content dispute, but don't use the term 'vandalism' because that will suggest you are a person who should not be taken seriously.

== Pseudoforests enumeration == |
|||
Hi, |
|||
I discovered pseudoforests accidentally some years ago working with a method of [[perfect hash]]. Since that time I called them quasiforests, in lack of a name to give to the graphs that appeared in my work. One day I see the article Pseudoforest in Wiki and I thank: It is well written, the definitions and properties are well structured, and better, now I have a “standard” terminology to communicate my work in hash. Because of that I wish to thank you for your time and your work on the subject. |
|||
A few days ago I wrote about numbers of distinct pseudoforests with cycles of length one. My text is no more in the article Pseudoforests. |
|||
Could you explain why? |
|||
Thanks in advance. |
|||

:There are two answers. One is that [[WP:NOR|Wikipedia isn't the place to publish new discoveries about the subjects of its articles]]. Your addition did include citations to OEIS for the sequences concerned, but did not have [[WP:RS|sources]] for the equality of these sequences with the numbers of pseudoforests you described, and your inclusion of a signature in your addition was also a sign in the same direction. The second answer, though, is that I think pseudotrees with cycles of length one (which is to say, trees in which one node has been distinguished from the others by the existence of a [[self-loop]]) are a very specialized subtopic more closely related to trees than to pseudotrees, and that the inclusion of that material in the article is [[WP:UNDUE|out of balance]] with its importance to the overall subject of pseudoforests. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 02:27, 25 January 2008 (UTC) |
|||
Hi, |
|||
I agree with your first answer. In the future, if I edit an article in Wiki directly, even a stub, I will not put a signature. I will also try to give sources. I am a neophyte in Wiki so perhaps I deserve the opportunity to fix errors. |
|||
I will write some stuff on pseudoforest enumeration. I will write on your talk page so if you want to edit my text, it will be less painful. You also will have the opportunity to try to dissuade me to add a text. I am not going to send a lot, after all, it appears that enumeration must be concise on the article, see below. |
|||
I understand that is not informative to write about numbers of pseudoforests with specific characteristics. One could, for example, insert OEIS results on the number of unicyclic graphs “of several types”. |
|||
I studied a uniform model of random multigraph generation, as in Janson and others<sup>1</sup>, starting with n vertices, and stopping when exactly n edges are added, i.e., with c = 1. |
|||
In this model, when m = n = 6, more than 12% of the random graphs are pseudoforests having only loops. The majority of those graphs, roughly 67%, are pseudotrees, and less than 5% have 3 pseudotrees. |
|||
For n = m = 13, the probability of a pseudoforest with loops drops to approximately 1%. Of course, for n = m = 1 all graphs are pseudoforests with loops. For n = 41, we have to try 913,532 times on the average to see a pseudoforest with loops. |
|||
When n tends to infinite, we know that for c > 1/2, i.e., for c << 1, almost every random graph with cn edges is not a pseudoforest, but in CS, for example, are we always interested only in asymptotic results? Those results fail up to what values of n? Unfortunately I cannot have now an answer for the case c ~1/2, c > 1/2, and pseudoforests “in general”, but for n = 50, I conjecture that more than half of the graphs are pseudoforests “of any kind”. |
|||
It is clear that pseudoforests with cycles of length one have a limited scope, |
|||
but aside of asymptotical results, there are any results about any kind of random pseudoforests? Probably no. However I now will not insist to add results on those forests. |

== Boolean algebra task force == |
|||
I'd like to invite you to participate in the [[WP:BATF|Boolean algebra |
|||
task force]] that I am forming. Despite the name, a task force is just an ''ad hoc'' subcommittee of a wikiproject to work on a particular issue. In this case, I think that our articles on various aspects of Boolean algebra, propositional logic, and applications would benefit from some big-picture planning of the organization of material into various articles. The task force would not require a great time commitment. The main goal is to work out a proposal for how the material should be arranged. A second goal is for the focus to remain interdisciplinary, including computer science, logic, and mathematics. — Carl <small>([[User:CBM|CBM]] · [[User talk:CBM|talk]])</small> 16:12, 28 January 2008 (UTC) |

Howdy, I noticed you disliked the early reliance on et al. in the {{tl|citation}} template. I too was bothered by it. I did not see a general, n-author, solution, but I upped the limit from 3 to 8.

|||
*<nowiki>{{User:JackSchmidt/Citation | last1=A | last2=B | last3=C | last4=D | last5=E | last6=F | last7=G | last8=H | year=2009 | title=Alphabet Soup }}</nowiki> |

|||
Hopefully one of the {{tl|citation}} authors will pick it up, but I wanted to check with you if it looked reasonable. You should be able to replace any <nowiki>{{Citation}}</nowiki> template with <nowiki>{{User:JackSchmidt/Citation}}</nowiki> and preview without change, except for the 4 or more authors.

==Pseudoforests== |
|||
I want to verify the term "pseudotree". By analogy with "pseudoforest" a pseudotree should have ''at most'' one cycle. I assume you're following precedent in defining it to have exactly one cycle. Am I right? I wonder how established that usage is? (I'm sorry, my copy of Dantzig is not handy. I'll be checking it for pseudos and disguised bicircular matroids!) [[User:Zaslav|Zaslav]] ([[User talk:Zaslav|talk]]) 07:46, 17 February 2008 (UTC) |
|||
:Try [http://scholar.google.com/scholar?num=20&hl=en&lr=&safe=off&q=pseudotree+pseudoforest&btnG=Search this Google scholar search]. The term seems to be used in two ways: the first hit (Kowalik) says at most one cycle, but the fourth (Fekete and Szego) uses the version with exactly one cycle. I didn't check carefully how often it is used in which sense. The article already states that the terminology is not very standardized but perhaps that could be made more clear.

Also, I assumed the alternate definition by number of edges is that a component has no more edges than vertices; this was worth adding, and I hope the reference you gave is the right one for it (but it probably isn't, since you have a different counting definition later; probably this should be re-edited). Smaller edits will follow, but if you have any problem with this, please let me know. |

== Subgraph isomorphism? == |
|||
Hi David, |
|||
I've recently found myself implementing a subgraph isomorphism algorithm for hypergraphs, where I have to also match the labels on the hypergraph edges and verticies. This is for a linguistics application, some English language semantic parsing. I was wondering if perhaps you'd seen any particularly good algorithms for this sort of thing. I can happily continue in my ad-hoc manner, but thought that perhaps there'd be benefit in some scholarly research as well. [[User:Linas|linas]] ([[User talk:Linas|talk]]) 19:20, 28 February 2008 (UTC) |
|||
:Unfortunately the algorithms I know the most about are more of theoretical than practical interest. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 06:42, 5 March 2008 (UTC) |
|||
::Thanks. I finished my code... my subgraph was presented as a list of trees, which shared nodes. Once I had this clearly in my head, it was a simple matter of trying to lay down one tree, and string all the others together to follow. Seems like this should have decent performance; I current can't imagine how to improve on it. [[User:Linas|linas]] ([[User talk:Linas|talk]]) 14:47, 6 March 2008 (UTC) |

::Do you know anything about category theory? I have a nutty question; but first an intro: [[Cartesian closed categories]] have [[lambda calculus]] as their, umm, language. Lambda calculus is "just" a bunch of symbols strung together, not associative or commutative, with a lambda symbol used to bind variables. One can do something similar with graphs: let me use a lambda symbol to bind certain nodes (or edges!?) as "variables"; and so, just as in lambda calculus, one may use these to nest graphs one in another, and also define reductions, etc. Seems like much of the mechanics of lambda calculus would just go across. I haven't quite grokked what the equivalent of a combinator would be, though. The question is this: 1) does the study of lambda-applied-to-graphs have a name (what keywords would folks publish under?) (I assume people have written books about this!?) and 2) what would the analogue of the Cartesian closed category be, in this case? Its not perhaps by accident a topos or anything like that? [[User:Linas|linas]] ([[User talk:Linas|talk]]) 14:47, 6 March 2008 (UTC) |
|||
:::No, I tend to avoid category theory. What I've seen of the theory looks pretty, but it's an area where I don't have a good intuition about what's just genuine progress vs what's just abstraction for the sake of abstraction. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 15:16, 6 March 2008 (UTC) |

The article states that "if {2,3,...} are partitioned into finitely many subsets, then one of the subsets can be used to form an Egyptian fraction representation of unity." My question is: is {2, 3, ...} the set of prime numbers or just the set of integers greater than 1? [[User:PrimeFan|PrimeFan]] ([[User talk:PrimeFan|talk]]) 00:58, 7 March 2008 (UTC) |

== [[Richard nixon]] == |
|||
Hi David, |
|||
You recently declined a speedy, noting "Redirect is from a natural misspelling and is properly tagged {{tl|R from other capitalisation}}". |
|||
The issue here is that although strictly speaking it's properly tagged, it's a useless redirect, in that nothing links to it and it adds nothing to the default behavior of the Go box -- if I type in "richard nixon" or "Richard nixon", the software will automatically convert this to "Richard Nixon" and take me to the right page. That is, the "natural misspelling" in this case is automatically and properly handled; there is no need to add potentially hundreds and thousands of redirects to handle this particular case for every multi-word proper name. |
|||
I've tagged similar redirects in the past (most recently [[Eliot spitzer]]), and they've been removed. (You can try typing "Eliot spitzer" or "eliot spitzer" and you'll see that nothing was lost by the redirect's removal.) |
|||
Clearly this is more a nit than anything -- I mainly propose these when I find them because it eliminates the odd "Redirected from John doe" message that appears when people enter a name in lowercase into the Go box. Would you be willing to reconsider? Thanks, [[User:NapoliRoma|NapoliRoma]] ([[User talk:NapoliRoma|talk]]) 18:37, 12 March 2008 (UTC) |
|||
:When I type "Eliot spitzer" into a url of the form http://wiki.riteme.site/w/index.php?title=... or http://wiki.riteme.site/wiki/..., though, I don't get redirected to the right place. I almost never use the Go box myself. If the mediawiki software automatically found the redirect when given the name as a URL, I'd be more convinced. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 18:41, 12 March 2008 (UTC) |
|||
::The logical extreme conclusion to this concept would be that there should then be "First last" redirects for every "First Last" in the encyclopedia. Why just have one for "Richard nixon"? Is his name more commonly hacked into a URL in lowercase than say, [[Dan Aykroyd]]'s? |
|||
::We'd also need to create the appropriate parallel URLs for Richard m nixon, Dick nixon, President nixon, Richard milhous nixon, Tricky dick nixon, President richard nixon, and so on -- all of these work today in the Go box in lower case, but none of them work in URLs in lower case. |
|||
::I agree with you that if "I should be able to hack proper names into URLs in lowercase" is a desired behavior, it should be fixed in the software, not by creating a ton of redirects. Regards, [[User:NapoliRoma|NapoliRoma]] ([[User talk:NapoliRoma|talk]]) 20:20, 12 March 2008 (UTC) |
|||
::Re-reading my above, I may have come off as more confrontatory than I intended. I just wanted to point out that this particular type of redirect is at best a band-aid compensating for a possible limitation in the mediawiki software -- and to carry the metaphor to its extreme, it's a 1" band-aid for a 5 mile scrape :-/...

::::Understood, thanks for the discussion.

I am trying to use Wiki to freely distribute my image, not make $ with it.

I think I have a grip on it now, and even if the page is deleted, I am thankful for the messaging because I got a crash course in copyright info, citing sources, and editing on wiki.

:The speedy tag got some attention to the article, so in that sense it was successful. Other possibilities would have been (1) to tag it with {{tl|unreferenced}} or {{tl|notability}} (not usually very effective), (2) to use {{tl|prod}} instead of a speedy deletion tag; then if nobody fixes it up within 5 days it can be deleted; (3) to take it to a full deletion discussion using {{tl|afd}}, or (4) (my favorite) do some searching to try to find more material to expand the article. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 05:41, 2 April 2008 (UTC) |

:Please refer to [http://wiki.riteme.site/w/index.php?title=Wikipedia:Administrators%27_noticeboard&diff=prev&oldid=202702209 this response I gave to someone else] recently who also objected to the removal of tags. The short answer is that you are mistaken: removal of tags may be appropriate in some cases, and may be inappropriate in others, but it is not vandalism (except for certain very specific tags, such as the afd notices). The only item in [[Wikipedia:Vandalism]] pertinent to tags is "Abuse of tags: Bad-faith placing of ... tags on pages that do not meet such criteria." For instance, your repeated application of {{tl|refimprove}} to articles that have perfectly adequate references might plausibly fall under this. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 23:39, 4 April 2008 (UTC) |

The list of authors must be there because this is a bio article. Bio articles should speak two things - the contributions and the life style which includes family memebrs and the one who worked closely with. That speaks the personality and then only the article is complete. Why do we have Erdos # mathematicians listed on Wikipedia? It carries a lots good memories. |
|||
I recommend you adding your family members and your famous students etc. on the Bio article you have on Wikipedia. |

:It would probably be best to wait until the book has been published and, more importantly, professionally reviewed, before writing about it, so you can cite the reviews as [[WP:RS|reliable sources]] that would establish the [[WP:N|notability]] of the subject. But in general, self-published books (and fictionpress, the site you linked to for the book, is a place where people self-publish) aren't generally considered notable enough for Wikipedia. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein#top|talk]]) 15:52, 6 April 2008 (UTC) |

Hi! I didn't write the Nick Savoy page but I worked on it extensively. I noticed that you voted to delete. I'm not sure if this sways your decision (which was made based on 'notability' but he is on the Dr Phil show tomorrow, April 11. I just saw him on TV as the Dr Phil show is promoting him extensively (www.drphil.com/shows). So now I have found: |
|||
* Dr Phil |
|||
* CBS National Radio |
|||
* Fox TV |
|||
* Playboy TV |
|||
* Brink Magazine |
|||
* Globe and Mail magazine (quoting him as an expert) |
|||
* Mentioned in other wikipedia pages such as Mystery Method |
|||
* As far back as 2006 there was some consensus to include him (http://wiki.riteme.site/wiki/Talk:Seduction_community) |
|||
Does the Dr Phil showchange your opinion? If not, what would? I would like to get the page back up; I worked really hard on it. Thanks so much for your time! [[User:Camera123456|Camera123456]] ([[User talk:Camera123456|talk]]) 23:52, 10 April 2008 (UTC) |

Hey David, I am doing stuff with style guidelines and WP:GAN these days, I would welcome your input any time. Notice that when I saw the current question at WT:CITE, I notified the WT:FAC folks right away. That seems like the right call, I don't think that's "canvassing", but do you think there are other groups who should also be notified to give input on similar issues?

== Ptolemy's Theorem == |
|||
Hello David |
|||
I submitted Proof 3 on this page because it is needed for the corollaries which follow from presenting Ptolemy's Theorem in trig form. I don't have a written source but I have no doubt there is one somewhere (there certainly is on the web) and am quite happy to reference it. |
|||
The corollaries are fairly obvious derivatives - it doesn't take a rocket scientist to work them out and I have no doubt that in principle what I have presented on the web page is no more than a regurgitation of material which is at least a couple of millenia old. I would not be at all suprised to find someone else has similarly reworked Copernicus/Ptolemy Thms 2,3,4,5 etc into modern trig format (eg Cut the Knot references) and once again would be more than happy to quote any such sources other than these 'originals'. |
|||
Referencing in this context is something of a problem - I have simply gone back to source as far as I am able: namely Copernicus in 'Liber Primum' of 'De Revolutionibus Orbium Coelestium' following Ptolemy in 'Almagest'. English translation of Copernicus as provided in Stephen Hawking's book 'On the Shoulders of Giants'. |
|||
In the examples section I have used the term 'ancient magi' in my submissions because I need once again to acknowledge a 'road well travelled'. How well travelled is I think a question open to debate since we have the curious anomaly of Copernicus/Ptolemy presenting and using Ptolemy's Theorem ('Theorema Secundum in DROC') in some detail whilst not - apparently - realising that 'Theorema Primum' could be relatively easily derived from it as shown in the 'Examples' section of the Wiki page. Instead the justification comes from a reference to some unecessarily complex Euclidian proofs. |
|||
In particular we need to understand - in ancient context - the statement that the "sum of squares of the sides of the (inscribed) hexagon and decagon equals the square of the side of the pentagon". In modern trig notation: |
|||
sin^2(18) + sin^2(30) = sin^2(36). |
|||
Resolving this may lead to yet another anomaly indicating that "Ptolemy's Theorem" may in fact precede Ptolemy and that is why I have followed the "ancient scribe" persona used on Leon Cooper's "Deep Secrets" site. If there is a 'less theatrical' means of acknowledgement, I am quite happy for the script to be altered accordingly and to otherwise deal with the concerns you have raised in whichever way is appropriate. |
