These problems are typically exponential in terms of time complexity and may require exploring all possible permutations in worst case.
In this monograph optimality is attained for nontrivially sized problems via the branch-and-bound paradigm.

However until now there has not been a single resource in statistical data analysis to summarize and illustrate available methods for applying the branch-and-bound. The Breath first search and depth-first search in which the exploration of a new node cannot begin until the node currently being explored is fully explored. Branch and bound method can be applied even in some cases of nonlinear programming.
The principle consists in partitioning the solution space into disjoint subsets which are represented by the nodes of the branching tree. The Branch and bound strategy is very similar to backtracking in that state space tree is used to solve a problem. Practical use of a branch-and-bound.

Further on the techniques of implicit enumeration can be incorporated easily in the branch and bound frame. This chapter describes the principles of branch and bound in combinatorial optimization and gives details of one of its applications. Then one can conclude according to the present state of science that no simple combinatorial algorithm can be applied and only an enumerative-type method can solve the problem in question.
