Title : New Perspectives on Explainable Optimization

Abstract :  In recent years, there has been a rising demand for transparent and explainable AI models. Although significant progress has been made in providing explanations for machine learning (ML) models, this topic has not received the same attention in the Operations Research (OR) community. However, algorithmic decisions in OR are made by complex algorithms which cannot be considered to be explainable or transparent as we will argue in this talk. To tackle this issue we present two promising concepts to provide explanations for (integer) optimization problems. In the first part we introduce the concept of counterfactual explanations and show how it can be used to calculate explanations for linear integer optimization problems. We show that the resulting problem is Sigma_2^p-hard but can be solved in reasonable time for certain special cases. In the second part we present a model-agnostic method called CLEMO which can provide explanations for any type of optimization algorithms (exact or heuristic). The idea is to approximate the input-output relationship of an optimization algorithm by an interpretable linear ML model.
