The following map WebThe next thing you should do is to solve two new integer programs, one in which x = 3 and one in which x = 4, and pick the better answer of the two as your solution to the original problem. c) After you have solved an LP in a branch-and-bound tree, what are the three conditions under which you would NOT split that node into two new nodes?

The naive way to solve an ILP is to simply remove the constraint that x is integer, solve the corresponding LP (called the LP relaxation of the ILP), and then round the entries of the solution to the LP relaxation. But, not only may this solution not be optimal, it may not even be feasible; that is, it may violate some constraint. While in general the solution to LP relaxation will not be guaranteed to be integral, if the ILP ha…
