Algorithms like MAP-Elites mimic this divergent evolutionary\nprocess to find a set of behaviorally diverse but high-performing solutions,\ncalled the elites. Our key insight is that species in nature often share a\nsurprisingly large part of their genome, in spite of occupying very different\nniches; similarly, the elites are likely to be concentrated in a specific\n\"elite hypervolume\" whose shape is defined by their common features. In this\npaper, we first introduce the elite hypervolume concept and propose two metrics\nto characterize it: the genotypic spread and the genotypic similarity. We then\nintroduce a new variation operator, called \"directional variation\", that\nexploits interspecies (or inter-elites) correlations to accelerate the\nMAP-Elites algorithm. We demonstrate the effectiveness of this operator in\nthree problems (a toy function, a redundant robotic arm, and a hexapod robot).","url_abs":"http://arxiv.org/abs/1804.03906v1","url_pdf":"http://arxiv.org/pdf/1804.03906v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"discovering-the-elite-hypervolume-by","repo_url":"https://github.com/resibots/vassiliades_2018_gecco","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":{"status":"ok","spdx":"GPL-3.0"}}],"tasks":[{"task_slug":"diversity","task_name":"Diversity"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1804.03906","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
