摘要:
针对标准的遗传算法收敛速度慢的特点做了几点改进:在群体初始化中,以均匀产生初始群体代替随机产生;实行截断选择,隐含了最优保存策略;动态变异,将改进后的遗传算法和系统识别原理相结合,应用于路面反分析中.分别对理论数据和实测数据进行了计算分析,并和目前国内国际较通用的软件计算结果进行了比较分析.结果表明,改进后的遗传算法收敛速度快,具有较强的全局优化能力,利用该算法进行路面反演可以避免解病态方程,反演结果稳定可靠.
Abstract:
Several improvements have been made to the slow convergence speed of standard genetic algorithms: in population initialization, uniform generation of initial population instead of random generation; The implementation of truncated selection implies the optimal preservation strategy; Dynamic variation, combining the improved genetic algorithm and system recognition principle, is applied to pavement inverse analysis. The theoretical data and the measured data were calculated and analyzed, and the calculation results of the software that are more common at home and abroad were compared and analyzed. The results show that the improved genetic algorithm has fast convergence speed and strong global optimization ability, and the pavement inversion using the algorithm can avoid solving the sick equation, and the inversion results are stable and reliable.
