摘要: In this paper we present CABRO, an algorithm for solving the winner determination problem related to single-unit combinatorial auctions. The is divided in three main phases. first phase a pre-processing step with some reduction techniques. second calculates upper and lower bound based on linear programming relaxation order delete more bids. Finally, third branch depth search where used as bounding sorting strategy. Experiments against specific solvers like CASS general purpose MIP GLPK CPLEX show that CABRO average fastest free solver (CPLEX not included), instances drastically faster than any other.
