(Dantzig-Wolfe LP) For the Questions 1 and 2, consider the following optimization problems. Write a Dantzig-Wolfe reformulation of this problem by convexifying X (i.e., using the extreme points of X ). Clearly write down the master problem and subproblem (pricing problem). Then, solve the problem using DW reformulation. No need to do all the iterations, you can stop after three iterations.
