In words, what we will do is successively solve continuous linear programming problems, but while imposing new inequality constraints that force the elements into taking integer values. The method uses two major concepts. The first has to do with bounds and is quite intuitive.

WebBranch and bound, or BnB, is an algorithm design paradigm that solves combinatorial and discrete optimization problems. Many optimization issues, such as crew scheduling, network flow problems, and production planning, cannot be solved in polynomial time. Hence, BnB is a paradigm that is widely used to solve such problems.
