Algorithms, Combinatorics and Optimization (ACO) is an elite multidisciplinary program sponsored jointly by the College of Computing, the H. Milton Stewart School of Industrial and Systems Engineering, and the School of Mathematics. The ACO Program sets very high standards for admission and graduation, and boasts world-class faculty with research interests spanning a wide expanse of topics, from ones purely theoretical to others more applied. The ACO Program curriculum provides required course work designed to ensure that students have a strong fundamental academic base that serves to facilitate and enhance their research options. We have essentially eliminated the traditional walls that usually separate academic units: any affiliated faculty member can supervise the research of any ACO student regardless of departmental affiliation. All we ask is that the work produced be first rate. ACO alumni have been very successful and have won prestigious awards from a variety of research and professional societies. Graduates of the PhD program can be found in myriad settings in both academe and industry; some have even chosen careers in finance.
