WebFigure 2: Pseudocode for backtracking search with forward checking. Constraint Propagation Figure 3 presents the pseudocode for the arc consistency algorithm (AC), the most basic form of constraint propagation. 2 The basic idea of the algorithm is to just check that all the arcs in the constraint graph are consistent. Web(CSP) algorithms, including forward checking, dynamic variable ordering, conflict-directed backjumping, and arc consistency. Past research has suggested these algorithms make for significantly more efficient CSP solvers. Although CSPs are in the class of NP-Complete problems, even fairly large instances of constraint satisfaction problems can be pool light deck junction box
