TORCH is a one-day contest organised by operations research students of three universities, Concordia, Toronto and Waterloo, where teams of 3 to 4 high school or CÉGEP students solve problems taken from different application areas of operations research.
I took part in the the Montréal edition of the third TORCH, at Concordia University, during my seconde year at the Collège Stanislas, in a team of 3 with two students in première.
We finished 6th out of 35 groups.
