We consider the maximum feasible subsystem problem in which, given an infeasible system of linear inequalities, one wishes to determine a largest feasible subsystem. The focus is on the version with bounded variables that naturally arises in several fields of application. To tackle this NP-hard problem, we propose a simple but efficient two-phase relaxation-based heuristic. First a feasible subsystem is derived from a relaxation (linearization) of an exact continuous bilinear formulation, and then a smaller subproblem is solved to optimality in order to identify all other inequalities that can be added to the current feasible subsystem while preserving feasibility. Computational results, reported for several classes of instances, arising from classification and telecommunication applications, indicate that our method compares well with one of the best available heuristics and with state-of-the-art exact algorithms.
