A branch-and-bound algorithm (BB for short) is the most general technique
to deal with various combinatorial optimization problems. Even if it is
used, computation time is likely to increase exponentially. So we
consider its parallelization to reduce it.
We can expect that obtaining a better incumbent
makes bounding operations appear at early stages
of computation, possibly resulting in short computation time.
In case of a parallel BB, it is also necessary to balance
each processor load and to prevent increase in communication time．
In this paper, we focus on a parallel BB for the graph coloring problem,
propose some improvements for it,
and experimentally
evaluate how our modification affect computation time of a parallel BB
on a PC cluster network. |
