M.S. THESIS PRESENTATION: Dual Representations of Quasiconvex Compositions with Applications to Systemic Risk

16/07/2021 @ 15:00 – 18:00 – The importance of measuring risk in an interconnected financial system has been appreciated recently, due in part to the global financial crisis. In the literature, systemic risk measures are generally represented by the composition of a univariate risk measure and an aggregation function, a function that encodes the structure of the financial network. Having dual […]

M.S. THESIS PRESENTATION: Examination Timetabling Problem

11/07/2021 @ 16:00 – 18:00 – Abstract: Examination timetabling is a major challenge in most educational institutions. Since the underlying problem is NP-hard and real-life problems are too hard to solve to optimality, heuristic approaches are adopted as solution methodologies in general. The significance of a fair exam schedule creates a need for exact solutions to the examination timetabling problem. In […]
