NK健身景观的瓶颈在哪里?

Where are Bottlenecks in NK Fitness Landscapes?

Sébastien Verel, Philippe Collard, Manuel Clergue

摘要:

通常,子代-亲代适应度相关性被用来可视化和分析适应度景观的一些特征,如可进化性。在本文中,我们介绍了这种相关性的一个更一般的表示,健身云(FC)。我们使用瓶颈的比喻,强调健身水平的景观,导致本地搜索过程减慢。对于局部搜索启发式,如爬山或模拟退火,FC允许可视化的瓶颈和中立的景观。为了确认FC表示的相关性,我们展示了众所周知的NK适应度景观中的瓶颈所在,以及如何使用FC的中立信息将一些中立算子与局部搜索启发式相结合。

英文摘要:

Usually the offspring-parent fitness correlation is used to visualize and analyze some caracteristics of fitness landscapes such as evolvability. In this paper, we introduce a more general representation of this correlation, the Fitness Cloud (FC). We use the bottleneck metaphor to emphasise fitness levels in landscape that cause local search process to slow down. For a local search heuristic such as hill-climbing or simulated annealing, FC allows to visualize bottleneck and neutrality of landscapes. To confirm the relevance of the FC representation we show where the bottlenecks are in the well-know NK fitness landscape and also how to use neutrality information from the FC to combine some neutral operator with local search heuristic.
