(English Abstract)
In combinatorial auctions, bidders can make bids on a set of items. When the items show complementarities in values, combinatorial auctions make it possible to express the values more accurately and enhance the market¡¯s efficiency. The winner determination problem is an NP-complete problem. To address this difficult and important problem, we can attempt to solve the special subproblem that can be solved efficiently or develop approximate solutions. In this paper, we reformulated the WDP into a knapsack problem. By using Markov chain Monte Carlo method, we achieved a desired stationary solution with a large objective function. The solution is comparable to that of integer programming
