Recent years have witnessed vigorous development in the application of mathematical and
computational techniques to many aspects of the organization and planning of sports …

In this paper, a new branch-and-price-and-cut algorithm is proposed to solve the one-
dimensional bin-packing problem (1D-BPP). The 1D-BPP is one of the most fundamental …

This study addresses a vehicle routing problem (VRP) in which demands are discrete, split
delivery is allowed, service time is proportional to the units of delivered products, multiple …

The sport teams grou** problem (STGP) concerns the assignment of sport teams to round-
robin tournaments. The objective is to minimize the total travel distance of the participating …

Abstract The Traveling Umpire Problem (TUP) is an optimization problem in which umpires
have to be assigned to games in a double round robin tournament. The objective is to obtain …

Operations researchers have long drawn insight from the structure of constraint coefficient
matrices (CCMs) for mixed integer programs (MIPs). We propose a new question: Can …

Given a double round-robin tournament, the Traveling Umpire Problem (TUP) seeks to
assign umpires to the games of the tournament while minimizing the total distance traveled …

In this paper, we study the multi-period inspector scheduling problem (MPISP). This problem
aims to determine a set of routes for a team of inspectors performing inspection jobs in …

Abstract The Traveling Umpire Problem (TUP) is a combinatorial optimization problem
concerning the assignment of umpires to the games of a fixed double round-robin …

Modern society pays more and more attention to leisure activities, and watching sports is
one of the most popular activities for people. In professional leagues, sports scheduling …
