Status: Accepted Owner: ---- Labels: Type-Defect Priority-Medium logic New issue 1545 by [email protected]: Efficient representation for data in logic.satisfiable() http://code.google.com/p/sympy/issues/detail?id=1545
Most SAT use an internal representation for CNF that is based on an array of integers, similar to the DIMACS cnf format[1]. Also, there is a patch by Ronan Lamy which speeds dpll by using sets instead of tuples (attached). We should investigate which is the best approach.
