| 摘 要： | 标准差分(SDE)算法具有算法简单、控制参数少、易于实现等优点,但容易发生早熟收敛。针对此缺点,提出一种改进的差分进化(IDE)算法。建立了铰链四杆函数发生机构近似运动综合的无约束优化模型,并应用IDE算法求解该优化问题。数值实例表明,IDE算法可以较好地克服早熟收敛问题,且能快速求出铰链四杆函数发生机构近似运动综合的优化解。 |

| Abstract: | The standard differential evolution (SDE) algorithm has the advantages of simplicity,few control parameters required,and easily be used,but has the disadvantage of premature convergence.The improved DE (IDE) algorithm is proposed to overcome the demerits of the SDE algorithm.An unconstrained optimization model is presented to approximately synthesize function generators of pin-jointed 4-bar linkages.And then,the IDE algorithm is utilized to solve this optimal problem for function synthesis.A numerical resul... |
