Improved Approximation Algorithms for Clustered TSP and Subgroup Planning

AAAI 2025technical

In the Clustered TSP (CTSP), we are given an edge-weighted graph satisfying the triangle inequality property, and a family of pairwise disjoint vertex groups. The goal is to find a minimum weight tour that includes all vertices, ensuring that the vertices within each group appear consecutively on t…

A Better Approximation for Bipartite Traveling Tournament in Inter-League Sports Scheduling

IJCAI 2024poster

The bipartite traveling tournament problem (BTTP) was initially introduced by Hoshino and Kawarabayashi (AAAI 2011) to address inter-league sports scheduling, which aims to design a feasible bipartite tournament between two n-team leagues under some constraints such that the total traveling distance…

Improved Approximation Algorithms for Capacitated Location Routing

IJCAI 2024poster

The Capacitated Location Routing Problem is an important planning and routing problem in logistics, which generalizes the capacitated vehicle routing problem and the uncapacitated facility location problem. In this problem, we are given a set of depots and a set of customers where each depot has an…

The Traveling Tournament Problem with Maximum Tour Length Two: A Practical Algorithm with An Improved Approximation Bound

IJCAI 2021poster

The Traveling Tournament Problem is a well-known benchmark problem in tournament timetabling, which asks us to design a schedule of home/away games of n teams (n is even) under some feasibility requirements such that the total traveling distance of all the n teams is minimized. In this paper, we stu…
