Abstract: The minimum reduction of decision tables is important in reduction learning , and it is also a combinatorial optimization problem. Many heuristic searching algorithms are discussed for the difficulty. In effect, however, the efficiency, robustness and completeness of minimum solutions etc. of the algorithms are hard to ensure. Based on rough sets and the extended matrix theory, this paper proposes a solution to overcome the disadvantages using GA(genetic algorithm). Examples show that the method seems to be both effective and can reach the optimal reduction at a high probability.
