WebJul 17, 2024 · BRANCH AND BOUND TECHNIQUE TO SOLVE ILP This is a type of divide and conquer method. The original problem is divided into multiple smaller problems (branching of a problem). ... EXAMPLE … WebBranch and Bound. The branch-and-bound method constructs a sequence of subproblems that attempt to converge to a solution of the MILP. The subproblems give a sequence of upper and lower bounds on the solution f T x. The first upper bound is any feasible solution, and the first lower bound is the solution to the relaxed problem.

Branch and bound (BB, B&B, or BnB) is a method for solving optimization problems by breaking them down into smaller sub-problems and using a bounding function to eliminate sub-problems that cannot contain the optimal solution. It is an algorithm design paradigm for discrete and combinatorial optimization problems, as well as mathematical optimization.
