Preen","Larry Bull"],"abstract":"We have recently presented an initial study of evolutionary algorithms used\nto design vertical-axis wind turbines (VAWTs) wherein candidate prototypes are\nevaluated under approximated wind tunnel conditions after being physically\ninstantiated by a 3D printer. That is, unlike other approaches such as\ncomputational fluid dynamics simulations, no mathematical formulations are used\nand no model assumptions are made. However, the representation used\nsignificantly restricted the range of morphologies explored. In this paper, we\npresent initial explorations into the use of a simple generative encoding,\nknown as Gielis superformula, that produces a highly flexible 3D shape\nrepresentation to design VAWT. First, the target-based evolution of 3D\nartefacts is investigated and subsequently initial design experiments are\nperformed wherein each VAWT candidate is physically instantiated and evaluated\nunder approximated wind tunnel conditions. It is shown possible to produce very\nclosely matching designs of a number of 3D objects through the evolution of\nsupershapes produced by Gielis superformula. Moreover, it is shown possible to\nuse artificial physical evolution to identify novel and increasingly efficient\nsupershape VAWT designs.","url_abs":"http://arxiv.org/abs/1204.4107v4","url_pdf":"http://arxiv.org/pdf/1204.4107v4.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":"towards-the-evolution-of-vertical-axis-wind","repo_url":"https://github.com/rpreen/superformula","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"3d-shape-representation","task_name":"3D Shape Representation"},{"task_slug":"evolutionary-algorithms","task_name":"Evolutionary Algorithms"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
