Abstract Based on binary particle swarm optimization, a minimum attribute reduction algorithm for a decision table is presented. A proper fitness function is defined. Thus, the minimum attribute reduction problem is equivalently transformed into a binary combinatorial optimization problem without additional nonlinear constraints. The concept of a seed particle is introduced with its protection strategy. Finally, an improved binary particle swarm optimization algorithm is proposed to solve the transformed problem. Experimental results show the effectiveness of the presented algorithm.
