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?
