摘要: 随着人工智能和大数据的迅猛发展,大数据的爆炸式增长和问题的复杂性分布导致对并行智能处理的要求日趋迫切.传统的理论模型和技术方法面临严峻挑战,受自然界启发的物理学法则和生物学方法逐渐成为研究热点.受多头绒泡菌的生长觅食等行为启发,提出了一种基于能量机制的多头绒泡菌动力学算法(physarum-energy dynamic optimization algorithm, PEO).该算法以多头绒泡菌算法为基础,根据其动力学特征,引入能量机制,以改进现有的多头绒泡菌算法全局信息交互能力差等缺点.此外,PEO引入了年龄因子的概念和扰动机制,以控制算法在不同阶段的寻优能力和收敛速度,并从理论角度对算法模型的收敛性进行证明.最后,通过在TSP数据集上实验证明算法在不同规模数据集的有效性和收敛性,并进行了参数分析.与其他的优化算法的对比实验数据表明,PEO在面对复杂问题的求解速度和收敛速度明显优于其他的优化算法,具有高精度和快收敛的特性.

Abstract: With the rapid development of artificial intelligence and big data, the explosive growth of big data and problem has grown in complexity, which leads to parallel intelligent computing demand increasing. Traditional theoretical models and methods are faced with severe challenges. Physics law and biological method inspired from nature has gradually become a hot spot in the present new period. Inspired by the foraging behavior of physarum, an dynamic algorithm based on energy mechanism is presented. Physarum-energy dynamic optimization algorithm (PEO) is being raised for overcome the drawbacks of physarum algorithm. According to physarum’s dynamic characteristics, the energy mechanism is introduced in PEO which aims to overcome the shortcomings of the existing physarum algorithm, such as its poor information interaction ability in whole. In addition, PEO develops age factor concept and disturbance mechanism, in order to adjust PEOs optimization ability and convergence speed in different age stages, and the convergence of algorithm model is proved through theoretical point of view. Finally, the validity and convergence of PEO are proved by experiments in TSP data set, and the main parameters of PEO are analyzed through experiments. When faced with complex problems, the simulation result comparison analysis between PEO and other optimization algorithms show that PEO is significantly better than other algorithm and PEO has the capability of high accuracy and fast convergence.
