Consider the following Integer Linear Programming (ILP) model Maximize Z = X1 + 4X2 Subject to X1 + X2 < 7 // Resource 1 X1 + 3X2 < 3 // Resource 2 X1, X2 > 0 X1, X2 are integer i. Consider using the Branch and Bound (B & B) technique to solve the ILP model. With the help of Tora software, draw the B & B tree. Always give priority for X1 in branching over X2. Clearly label the constraint on each branch. Branch and Bound (B & B) tree: ii. According to the B & B tree you draw in part (i), does the first level give any integer feasible solution? - If your answer is yes, write this solution - If your answer is no, Justify why.
