Experimental Matching of Instances to Heuristics for Constraint Satisfaction Problems

Table 7

Head-to-head comparison of DHS and each heuristic. The results indicate the percentage of saved consistency checks per test grid by using DHS with respect to each particular heuristic (negative numbers indicate increases in the percentage of consistency checks).
