Summary

Other BDD pictures:

The following is the RML (Relational Manipulation Language) code that I fed to CrocoPat to produce the GraphViz dot files:

// RML program to generate a BDD graph for the formula
// !x1 & !x2 & !x3  |  x1 & x2  |  x2 & x3,
// using the variable ordering <x1, x2, x3>.
// "crocopat -e BDD_simple.rml" generates a file in dot format.
// "dot -Tsvg BDD_simple.dot -o BDD_Variable_Ordering_Bad.svg"
// generates a file in SVG format from the file in dot format.

// There are two ('Boolean') values for the variables x1, x2, x3.
DOM("0");
DOM("1");

// F is the name of the Boolean formula.
F(x1,x2,x3) :=  (x1="0" & x2="0" & x3="0") 
              | (x1="1" & x2="1")
              | (x2="1" & x3="1");

// Prints the BDD as graph in GraphViz dot format.
PRINT GRAPH( F(x1,x2,x3) ) TO "BDD_simple.dot";
