In addition, the belief abstraction method and replanning scheme guarantee finding a feasible solution to the stochastic optimal control problem.\u0026nbsp;The novel belief abstraction method does not suffer from the curse of dimensionality. Also, performance of the algorithm does not degrade at the presence of nonlinear dynamics and non-Gaussian uncertainty.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Path Planning for Underwater Vehicle in Ocean Flow Field"}],"uid":"28475","created_gmt":"2020-12-08 19:22:30","changed_gmt":"2020-12-08 19:22:30","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-12-09T10:00:00-05:00","event_time_end":"2020-12-09T12:00:00-05:00","event_time_end_last":"2020-12-09T12:00:00-05:00","gmt_time_start":"2020-12-09 15:00:00","gmt_time_end":"2020-12-09 17:00:00","gmt_time_end_last":"2020-12-09 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
