WebTherefore, X < Y is satisfied for all possible pairs of values in the domains of X and Y, and the CSP is already arc-consistent. In general, binary CSPs can be made arc-consistent by applying the arc consistency algorithm, which involves iteratively removing inconsistent values from the domains of the variables until all constraints are satisfied.
