While some of these as the Shortest Pathproblem and the Minimum Spanning Tree problem have polynomial algo-ritms, the majority of the problems in addition share the property that nopolynomial method for their solution is known.

the Quadratic Assignment problem. 1 Introduction. Solving NP-hard discrete optimization problems to optimality is often an im-mense job requiring very e cient algorithms, and the B&B paradigm is one of the main tools in construction of these. A B&B algorithm searches the complete space of solutions for a given problem for the best solution.
