Abstract
In this paper, we propose a new iterative randomized rounding algorithm for approximately solving the k-clustering minimum completion problem. The problem is defined in the telecommunication field where an instance of the problem is characterized by a bipartite graph G(S, C, E). S represents a set of services, C denotes a set of clients and E is a set related to the links between elements of C and S. The problem is to partition the initial graph into k-clusters such that each cluster is a complete bipartite subgraph. The goal is to minimize added edges to make a complete sub bipartite graph. The proposed algorithm is based upon two phases: (i) rounding a series of fractional variables, augmented with (ii) a constructive hill-climbing procedure. Both phases are embedded into an iterative search forming an iterative randomized search. The performance of the proposed method is evaluated on a set of benchmark instances taken from the literature. Provided bounds are compared to those reached by the best methods available in the literature. Encouraging results have been provided.
