Milton Stewart\nSchool of Industrial and Systems Engineering, has received the prestigious National\nScience Foundation (NSF) CAREER Award for his work on non-traditional cutting-plane\nalgorithms for mixed-integer programs.\u003C\/p\u003E\n\n\u003Cp\u003EThe NSF offers this award as part of the Faculty Early\nCareer Development (CAREER) Program in support of junior faculty who exemplify\nthe role of teacher-scholars through outstanding research, excellent education,\nand the integration of education and research within the context of the mission\nof their organizations.\u003C\/p\u003E\n\n\u003Cp\u003EDey received this award for his research to improve the\ncurrent generation of mixed-integer programming (MIP) solvers by devising new\ngeneral-purpose cutting-plane methods. A great deal of useful information that\ncould be used in deriving and selecting cutting-planes is often left unused by\nstate-of-the-art MIP techniques. This project investigates some of the\nfollowing non-traditional paradigms for incorporating more information into\ncutting planes: (i) Use information from multiple constraints simultaneously to\nderive cutting planes, instead of using a single implied constraint. (ii)\nDesign suitable cutting planes and then verify their validity before use,\ninstead of deriving cutting planes without any control over their quality.\n(iii) Incorporate information from explicit enumeration of integer points to\nguide the choice of cutting planes and improve their strength. Since many\nmathematical challenges need to be overcome in order to tap the potential of\nthese non-traditional paradigms, results from this project could significantly\nenhance the mathematical toolkit used by integer programmers for the generation\nand analysis of cutting planes. \u003C\/p\u003E\n\n\u003Cp\u003EDey suggested this project will not only make theoretical\nadvances in mathematical programming, but also lead to significant improvements\nin the performance of MIP solvers, leading to huge gains in a broad spectrum of\napplications of MIPs. A key educational objective is to develop an operations\nresearch puzzle competition to foster and enrich an environment for\nundergraduate research. He would also like to design a new graduate course with\nthe aim of disseminating research results directly to future practitioners and\nto bring students from different engineering communities together, thus\nproviding opportunities for new research directions and collaborations.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ESantanu Dey, assistant professor in ISyE, has received the prestigious National\nScience Foundation CAREER Award for his work on non-traditional cutting-plane\nalgorithms for mixed-integer programs.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":"","uid":"27511","created_gmt":"2012-01-18 09:11:08","changed_gmt":"2016-10-08 03:10:57","author":"Ashley Daniel","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2012-01-18T00:00:00-05:00","iso_date":"2012-01-18T00:00:00-05:00","tz":"America\/New_York"},"extras":[],"hg_media":{"50244":{"id":"50244","type":"image","title":"Santanu Dey","body":null,"created":"1449175437","gmt_created":"2015-12-03 20:43:57","changed":"1475894471","gmt_changed":"2016-10-08 02:41:11","alt":"Santanu Dey","file":{"fid":"128820","name":"Dey_Santanu_-_Bust.jpg","image_path":"\/sites\/default\/files\/images\/Dey_Santanu_-_Bust_1.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/Dey_Santanu_-_Bust_1.jpg","mime":"image\/jpeg","size":3018606,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/Dey_Santanu_-_Bust_1.jpg?itok=v_l3r9rh"}}},"media_ids":["50244"],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[{"id":"134","name":"Student and Faculty"}],"keywords":[{"id":"9413","name":"CAREER Award"},{"id":"1202","name":"H.
