 Abstract:
Multiobjective optimisation is one of the earliest fields of study in operations research. In fact, Francis Edgeworth (18451926) and Vilfredo Pareto (18481923) laid the foundations of this field of study over one hundred years ago. Many real worldproblems involve multiple objectives. Due to conflict between objectives, finding a feasible solution that simultaneously optimises all objectives is usually impossible. Consequently, in practice, decision makers want to understand the trade off between objectives before choosing suitable solution. Thus, generating many or all efficient solutions, i.e., solutions in which it is impossible to improve the value of one objective without a deterioration in the value of at least one other objective, is the primary goal in multiobjective optimisation. In this talk, I will focus on Multiobjective Integer Programs (MOIPs) and explain briefly some new efficient algorithms that I have developed since starting my PhD to solve MOIPs. I also explain some links between the ideas of multiobjective integer programming and other fields of study such as game theory.
