Two exact algorithms for the traveling umpire problem

Xue, Li; Luo, Zhixing; Lim, Andrew - In: European Journal of Operational Research 243 (2015) 3, pp. 932-943

In this paper, we study the traveling umpire problem (TUP), a difficult combinatorial optimization problem that is formulated based on the key issues of Major League Baseball. We introduce an arc-flow model and a set partition model to formulate the problem. Based on these two models, we propose...
