Weband CDCL algorithms have emerged and can handle practical SAT instances with millions of variables in reasonable running time. However, SATsolver implementations contain complex datastructures andalgorithms and canthere-fore contain subtle bugs. This is less of an issue for satisfiable instances, since a satisfiability certificate WebCDCL (:P1;N;;;1;>) The algorithm jumps through variable Pto its clause sequence on the right, because all clauses to the left of P are true. It nds the two literal clauses P_:R, …

WebDLL/CDCL Algorithms Today: Exploration + Generalization • EXPLORATION: Iteratively set variables until – you find a satisfying assignment (done!) – you reach a conflict (backtrack and try different value) • GENERALIZATION – When a conflict is reached, LEARN a clause that “remembers” the reason for the conflict
In computer science, conflict-driven clause learning (CDCL) is an algorithm for solving the Boolean satisfiability problem (SAT). Given a Boolean formula, the SAT problem asks for an assignment of variables so that the entire formula evaluates to true. The internal workings of CDCL SAT solvers were inspired by … See more Boolean satisfiability problem The satisfiability problem consists in finding a satisfying assignment for a given formula in conjunctive normal form (CNF). An example of such a formula is: ( (not A) or (not C) ) … See more The main application of CDCL algorithm is in different SAT solvers including: • MiniSAT • Zchaff SAT • Z3 See more Related algorithms to CDCL are the Davis–Putnam algorithm and DPLL algorithm. The DP algorithm uses resolution refutation and it has potential memory access … See more Conflict-driven clause learning works as follows. 1. Select a variable and assign True or False. This is called decision state. Remember the … See more DPLL is a sound and complete algorithm for SAT. CDCL SAT solvers implement DPLL, but can learn new clauses and backtrack non-chronologically.
