A General Heuristic Approach for Maximum Polygon Packing (CG Challenge)

Authors: Canhui Luo, Zhouxing Su, and Zhipeng Lü

Published in: LIPIcs, Volume 293, 40th International Symposium on Computational Geometry (SoCG 2024)

Abstract

This work proposes a general heuristic packing approach to address the Maximum Polygon Packing Problem introduced by the CG:SHOP 2024 Challenge. Our solver primarily consists of two steps: (1) Partitioning the container and polygons to form a series of small-scale subproblems; (2) For each subproblem, sequentially placing polygons into the container and attempting to eliminate overlaps.

PACE Solver Description: Hust-Solver - A Heuristic Algorithm of Directed Feedback Vertex Set Problem

Abstract

A directed graph is formed by vertices and arcs from one vertex to another. The feedback vertex set problem (FVSP) consists in making a given directed graph acyclic by removing as few vertices as possible. In this write-up, we outline the core techniques used in the heuristic feedback vertex set algorithm, submitted to the heuristic track of the 2022 PACE challenge.
