在进化计算问题中,问题难度的一个关键指标是景观的局部性,即基因型-表型映射是否保持邻域。在遗传规划中,基因型和表型是不明显的,但基因型适应度映射的局部性是感兴趣的。在本文中,我们扩展了原来的标准定量定义的地方,以涵盖基因型适应度的情况下,考虑三种可能的定义。通过将这些定义所给出的值与进化运行的结果相关联,我们研究了哪个定义作为性能的预测器是最有用的。
A key indicator of problem difficulty in evolutionary computation problems is the landscape's locality, that is whether the genotype-phenotype mapping preserves neighbourhood. In genetic programming the genotype and phenotype are not distinct, but the locality of the genotype-fitness mapping is of interest. In this paper we extend the original standard quantitative definition of locality to cover the genotype-fitness case, considering three possible definitions. By relating the values given by these definitions with the results of evolutionary runs, we investigate which definition is the most useful as a predictor of performance.
