public interface SuborderSearch

An interface for suborder searches for various types of permutation algorithms. A "suborder search" is a search for permutation <x1a,...x1n, x2a,...,x2m, x3a,...,x3l>> that searches for a good permutation of x2a,...,x2m with x1a,...,x1n as a prefix. This is used by PermutationSearch to form a complete permutation search algorithm, where PermutationSearch handles an optimization for tiered knowledge where each tier can be searched separately in order. (See the documentation for that class.)

This class is configured to respect knowledge of forbidden and required edges, including knowledge of temporal tiers.
