We improve a branch-and-bound algorithm called MCT(Tomita et al., FAW 2016, LNCS 9711, pp.215-226, 2016) for finding a maximum clique. First, we devise a new efficient approximation algorithm for finding a maximum clique. Second, we employ MIS vertex ordering with an appropriate precondition. Third, we employ a combination of Re-NUMBER and Infra-chromatic bound. Finally, we devise an adaptive change of stages of the search tree. The finally improved MCT algorithm is named MCT*. It is shown that MCT* algorithm is significantly faster than MCT by extensive computational experiments. In addition, it is shown that MCT* algorithm is faster than the state-of-the-art IncMC2 algorithm(Li et al., INFORMS J. Computing, 30, pp. 137-153, 2018)for many instances. |
