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.

In forward checking, when some variable is assigned value, backtracking search does the following two things: It calculates each unassigned variable that neighbors that variable. 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.
