中文摘要: 在面向复杂问题求解的优化计算模型中如何建立全局与局部搜索之间的动态平衡,提升算法在收敛性前提下的综合计算性能,是自然计算模型研究中的关键问题。有鉴于此,课题组通过观察、抽象,进而模拟自然现象的降雨过程,探讨一种新型、高效的自然计算模型(雨滴计算)的实现方法,以提升计算模型在多变环境条件下的自适应能力,以及解决在相对复杂背景下的应用模式发现和自组织优化等问题。特别是通过对自然降雨过程的抽象,提取人工雨滴模型的特征和作用机理,在刨析全局与局部两种不同性质的搜索过程之间平衡机制的基础上,设计雨滴计算模型的相关规则。在此基础上,进一步通过针对多模函数优化、多目标优化等问题的仿真研究,分析模型中相关参数、算子等对问题求解的作用规律,从而指导算法在实际问题中的应用。最后,通过取得具有我国知识产权的研究成果,在所属研究方向上建立具有一定国际影响力的学术观点,为后续的研究工作创造条件。

英文摘要: As we know, it is a key problem in the research of Nature Inspired Computation, that how to set up a self-correcting homeostasis mechanism between the global and the local searching process, and to improve the whole computing ability of finding the optimal solution for complex problems solving with the condition of convergence. Based on the consideration above, this project aims at designing a novel nature inspired model, namely the Raining Computation Model (RCM for the short), for optimization with high computing capacity. Through observing, abstracting and simulating the natural raining process, RCM is inspired by the dynamic process of rain and raindrops getting vertical radial local flow affected by gravity along the terrain, in order to enable its self-adaptation in frequently changing conditions, and to get the ability of surrounding pattern recognition and self-organization under a complex environment. To be more detailed, RCM simulates natural phenomenon such as condensation, diffusion, flow and gather of raindrops, in which the production of new raindrops is based on raindrop's relative distance, and uses a semi-certainty search pattern that raindrops randomly generated make global search with uncertainty and diffusion operation has an effect on neighborhood so that local search direction is determine
