Abstract(in Japanese) (See Japanese page)
Abstract(in English) Combinatorial optimization problems are widely exist. Generally they are solved by approximate means like greedy method because they are categorized as NP-hard. However, in several cases, the solution is likely to be local optimized. In the worst case, no solutions can be obtained. Meanwhile, even if brute force method like enumeration method is used, there is a possibility that optimized solutions can be obtained within realistic time because of resent performance improvement of processors and other reasons. For speeding up the enumeration method, a method of fast combination generation is required. In this paper, we clarify the problems for speeding up of enumeration method through performance evaluations of existing combination generation algorithms. Moreover, we propose a faster combination generation algorithm than existings. In the results of the performance evaluations, the dedicated hardware of the proposed algorithm achieves about 500 times faster than software of the existing algorithm and about 10 times than the dedicated hardware of that.
