Fast Propositional Algorithms for Planning

Fast Propositional Algorithms for Planning. Fast stochastic algorithms for propositional satisfiability: GSAT, WSAT (WalkSAT) Compile a planning problem in to a satisfiability problem (example of a constraint satisfaction problem -- CSP), and use a fast algorithm for satisfiability.
