--- abstract: 'Neural network-based controllers are evolved for racing simulated R/C cars around several tracks of varying difficulty. The transferability of driving skills acquired when evolving for a single track is evaluated, and different ways of evolving controllers able to perform well on many different tracks are investigated. It is further shown that such generally proficient controllers can reliably be developed into specialized controllers for individual tracks. Evolution of sensor parameters together with network weights is shown to lead to higher final fitness, but only if turned on after a general controller is developed, otherwise it hinders evolution. It is argued that simulated car racing is a scalable and relevant testbed for evolutionary robotics research, and that the results of this research can be useful for commercial computer games.' altloc: - http://julian.togelius.com/Togelius2006Evolving.pdf chapter: ~ commentary: ~ commref: ~ confdates: 'July 16-21, 2006' conference: IEEE Congress on Evolutionary Computation confloc: 'Vancouver, Canada' contact_email: ~ creators_id: [] creators_name: - family: Togelius given: Julian honourific: '' lineage: '' - family: Lucas given: Simon M. honourific: '' lineage: '' date: 2006 date_type: published datestamp: 2006-10-15 department: ~ dir: disk0/00/00/52/19 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 5219 fileinfo: /style/images/fileicons/application_pdf.png;/5219/1/Togelius2006Evolving.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: ~ lastmod: 2011-03-11 08:56:39 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: FALSE publication: ~ publisher: IEEE Press refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 12 series: ~ source: ~ status_changed: 2007-09-12 17:08:05 subjects: - comp-sci-mach-learn - comp-sci-neural-nets - comp-sci-art-intel succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: Evolving robust and specialized car racing skills type: confpaper userid: 4535 volume: ~
