Abstract: End-users of system solving combinatorial optimization problems such as the Workforce Scheduling and Routing Problem usually do not have the necessary background for understanding the reasons which has lead the system to output specific solutions and may have questions about them, especially questions about nonexpected facts observed in the solutions. Developing techniques to automatically generate explanations in response to end-users questions would then help enhancing their understanding of the results and preserve their trust in the system. In this paper, we propose a new mathematical programming-based approach to compute counterfactual explanations in response to end-users’ questions. Such explanations emphasize the few changes that may be operated on the instance data for obtaining solutions corresponding to the end-users’ expectations.
