Assume that you are provided with the score matrix S, detections can only be matched to a single track, and that tracks cannot be assigned more than once. (a) [5 points] What do the variables in this problem represent? How many are there? (b) [10 points] Define the objective for this 0-1 integer linear program. (c) [15 points] Define the entire 0-1 integer linear program, including constraints, in standard form. How many constraints are there in the program, total?
