A Hybrid Reinforcement Learning Algorithm for 2D Irregular Packing Problems
WebThe strip packing problem is a 2-dimensional geometric minimization problem. Given a set of axis-aligned rectangles and a strip of bounded width and infinite height, determine an … WebThe two-dimensional strip packing problem (2SP) is a well-known combinatorial optimization problem. It has several industrial applications like the cutting of rolls of paper or textile material. Moreover, some approximation algorithms for bin packing problems are in two phases where the first phase aims to solve a strip packing problem [ 1 , 2 ]. WebJan 8, 2024 · Packing problems, also known as nesting problems or bin packing problems, are classic and popular NP-hard problems with high computational complexity. Inspired by classic reinforcement learning (RL), we established a mathematical model for two-dimensional (2D) irregular-piece packing combined with characteristics of 2D irregular … mid city auto body newark ohio
