A Hybrid Scatter Search/Electromagnetism Meta-Heuristic For Project Scheduling, Dieter Debels, Bert De Reyck, Roel Leus, Mario Vanhoucke

Research Collection Lee Kong Chian School Of Business

In the last few decades, several effective algorithms for solving the resource-constrained project scheduling problem have been proposed. However, the challenging nature of this problem, summarised in its strongly NP-hard status, restricts the effectiveness of exact optimisation to relatively small instances. In this paper, we present a new meta-heuristic for this problem, able to provide near-optimal heuristic solutions for relatively large instances. The procedure combines elements from scatter search, a generic population-based evolutionary search method, and from a recently introduced heuristic method for the optimisation of unconstrained continuous functions based on an analogy with electromagnetism theory. We present computational …

It’S Not About The Money: The Role Of Preferences, Cognitive Biases And Heuristics Among Professional Athletes, Michael Mccann

Law Faculty Scholarship

Professional athletes are often regarded as selfish, greedy, and out-of-touch with regular people. They hire agents who are vilified for negotiating employment contracts that occasionally yield compensation in excess of national gross domestic products. Professional athletes are thus commonly assumed to most value economic remuneration, rather than the love of the game or some other intangible, romanticized inclination.

Lending credibility to this intuition is the rational actor model, a law and economic precept which presupposes that when individuals are presented with a set of choices, they rationally weigh costs and benefits, and select the course of action that maximizes their …

Social Psychology, Calamities, And Sports Law, Michael Mccann

Law Faculty Scholarship

This Article examines the role of situational pressures, fundamental attribution errors, and legal frameworks in how professional sports actors respond to the threat and occurrence of calamities. Both natural and manmade threats to American health are likely to rise over the next decade. Such threats may include catastrophic weather, natural disasters, terrorist attacks, and communicable disease pandemics. In response to these threats, professional sports leagues, professional athletes, fans, and media might engage in unprecedented behavior. Consider, for instance, increasingly-devastating weather patterns, and how they might animate leagues to relocate franchises to cities with more favorable forecasts. The same outcome might …
