Objective function design in real-number-coding genetic algorithm for laser-cutting tool-path minimization

Abstract

Laser-cutting path arrangements are constrained multimodal optimization problems. In solving these continuous-path control problems, one can improve the time efficiency and power consumption of laser-cutting process. This chapter presents a simplified objective function design methodology for real-number-coding genetic algorithm. In the cutting route determination stage, all the cutting starting and ending points are placed in a plane at the same place to facilitate the completion of routing. These objective functions can be used for path finding in practical laser-cutting assignments. © 2013 Springer Science+Business Media New York.
