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. Webthat forward checking does. No. While forward checking is a subset of arc consistency, after any assignment, arc consistency may have already eliminated values in a previous step that are eliminated in that step by forward checking. Thus, enforcing arc consistency will never leave more domain values than enforcing forward checking, but on a given
