Premios y Distinciones

  •   First Prize, Student Paper Competition

    Canadian Operational Research Society (CORS)

    Canada, 2020

    Each year CORS conducts a student paper competition to recognize the contribution of a paper either directly to the field of operational research through the development of methodology or to another field through the application of operational research. The competition serves to showcase the high quality of OR education in Canada as well as the excellence of the new generation of operational researchers. Prizes are awarded in two categories: Undergraduate and Open. Open Category First Prize: "A Combinatorial Cut-and-Lift Procedure with an Application to 0-1 Chance Constraints" Margarita Castro (University of Toronto)
