Description

Toulbar2-VACINT uses an initial upper bound solution found by INCOP local search. Next, the solver enforces Virtual Arc Consistency in preprocessing. A hybrid best-first search method is performed, restarting from the root after a given backtrack number and following VAC-integrality/Full-EAC variable ordering heuristic. The solver also applies a VAC-based upper bound probing heuristic to find good solutions in preprocessing. Toulbar2

The results below are organized as follows:

  • each table displays the solver’s normalized score for individual problem instances (and the associated log10 likelihood value) for the given task under different time limits
  • table values are normalized scores for each evaluated problem as outlined in Evaluation Criteria
