Particle swarm optimization based degree reduction of rational Bézier curves
基于微粒群算法的有理Bézier曲线降阶

By means of optimization methods, degree reduction of rational Bézier curves has been transformed to an optimization problem. Based on Particle Swarm Optimization (PSO) algorithm, a new method was proposed to solve the problem of degree reduction of rational Bézier curves. By using this method, the rational Bézier curves can be reduced many times and the reduced B zier curves can be represented explicitly. The PSO algorithm was compared with genetic algorithm, and the experimental results show that PSO algorithm is more effective.
