So we have to add two non-negativity contraints, x1 >= 0 x2 >= 0 The problem is now in the standard form for linear programming problems: an objective function that is to be maximized, subject to a ...

Integer linear programming can help find the answer to a variety of real-world problems. Now researchers have found a much faster way to do it. The traveling salesperson problem is one of the oldest ...

Specifically, when the ambiguity set constitutes a 2-Wasserstein ball centered at a discrete distribution, the distributionally robust linear program is equivalent to a copositive program (if the ...

The paper surveys the progress that has been made with the problem of solving linear programming problems when some or all variables are required to take integer values. It is pointed out that there ...
