基于模因的问题求解进化优化

Meme as Building Block for Evolutionary Optimization of Problem Instances

Liang Feng, Yew Soon Ong, Ah Hwee Tan, Ivor Wai-Hung Tsang

摘要:

在文献中,进化优化的一个显着不足的探索领域是可以随着问题的解决而进化的优化方法的研究。特别是,目前的进化优化方法通常从头开始搜索或从零开始的知识状态,独立于给定的新的感兴趣的问题是如何类似于那些以前优化。因此,显然缺乏跨问题的自动知识转移和重用。以此为线索,本文介绍了一种新的模因计算范式的搜索,一个模型后,人类如何解决问题,并开始对智能进化优化问题的研究,通过转移的结构化知识的形式模因从以前的解决问题的经验,以提高未来的进化搜索。模因搜索范式由模因学习、模因选择、模因变异和模因模仿四个文化启发算子组成。学习算子从过去解决问题的经验中挖掘潜在结构形式的模因。选择算子识别在问题间复制和传播的适合模因,而变异算子将创新引入模因。另一方面,模仿算子定义了合适的模因如何同化到新遇到的问题的搜索过程中,从而实现高效和有效的进化优化。最后,全面研究两个广泛研究的挑战性以及建立NP难路由问题域,特别是,有能力的车辆路由(CVR)和有能力的弧路由(CAR),证实了高效率的智能进化优化问题的模因计算搜索范式。

英文摘要:

A significantly under-explored area of evolutionary optimization in the literature is the study of optimization methodologies that can evolve along with the problems solved. Particularly, present evolutionary optimization approaches generally start their search from scratch or the ground-zero state of knowledge, independent of how similar the given new problem of interest is to those optimized previously. There has thus been the apparent lack of automated knowledge transfers and reuse across problems. Taking the cue, this paper introduces a novel Memetic Computational Paradigm for search, one that models after how human solves problems, and embarks on a study towards intelligent evolutionary optimization of problems through the transfers of structured knowledge in the form of memes learned from previous problem-solving experiences, to enhance future evolutionary searches. In particular, the proposed memetic search paradigm is composed of four culture-inspired operators, namely, Meme Learning, Meme Selection, Meme Variation and Meme Imitation. The learning operator mines for memes in the form of latent structures derived from past experiences of problem-solving. The selection operator identifies the fit memes that replicate and transmit across problems, while the variation operator introduces innovations into the memes. The imitation operator, on the other hand, defines how fit memes assimilate into the search process of newly encountered problems, thus gearing towards efficient and effective evolutionary optimization. Finally, comprehensive studies on two widely studied challenging well established NP-hard routing problem domains, particularly, the capacitated vehicle routing (CVR) and capacitated arc routing (CAR), confirm the high efficacy of the proposed memetic computational search paradigm for intelligent evolutionary optimization of problems.
