Using a tabu search approach for solving the two-dimensional irregular cutting problem

TL;DR: A new approach to cutting a rectangular sheet of material into pieces of arbitrary shapes is presented and a tabu search is applied for finding a final cutting pattern.
Journal ArticleDOI

Parallel tabu search approaches for two-dimensional cutting

TL;DR: A tabu search based approach as a method for solving in parallel the two-dimensional irregular cutting problem and efficiency measures for parallel implementations, where IBM SP2 and CRAY T3E systems have been used.
Journal ArticleDOI

TL;DR: In this article, a two-dimensional irregular cutting problem is considered and two new approximation algorithms based on tabu search and simulated annealing have been proposed and implemented and compared.
Journal ArticleDOI

A general purpose lossless data compression method for GPU

TL;DR: The paper describes a parallel method for a lossless data compression that uses graphical processing units (GPUs) and achieves a better compression speed than a standard CPU-based compression tools used in personal computers.

Two-Dimensional Cutting Problem

TL;DR: A decision support system for cutting a rectangular sheet of material into pieces of arbitrary shapes, which uses two earlier described methods which prefer different types of data and the user may decide which one is more suitable for the problem in question.
