The biclique k-clustering problem in bipartite graphs and its application in bioinformatics

Abstract In this paper we study the biclique k -clustering problem (B k CP) in bipartite graphs, a generalization of the maximum edge biclique problem which has several applications in biological data analysis. We present an application of the B k CP in bioinformatics, and introduce two integer linear formulations for the problem. Finally, we discuss the approximability of the problem and show computational experiments with random generated instances and also with instances that come the application.
