- I am looking for information on algorithms to solve the
- "boolean satisfiability problem". What is the largest problem that
- can be solved routinely? What is the best known algorithm?
- Any good references?
-
- The "boolean satisfiability problem" is a well-known NP-complete problem.
-
- A boolean function is expressed as a product of sums, for example
-
- F(a,b,c,d,...) = (a | ~b | c)&(~a | d | ~e)&...
-
- where the variables can take on the values TRUE and FALSE, and '|' represents
- logical or, and '&' represents logical and. The problem to be solved is:
- does any assignment of values to the variables cause the boolean function
- F(...) to be TRUE?
