00001 /** 00002 * \file PermutationSampler.h 00003 * \brief The class samples all permutations in a discrete set 00004 * to particles. Each anchor point can be mapped to one 00005 * particle for a specific mapping. For example, for anchor points 00006 * [1,2,3,4,5,6] to particles [a,b,c,d] the sampling space would be: 00007 * [1,2,3,4],[1,2,3,5],[1,2,3,6],[1,2,4,3],......,[6,5,4,2],[6,5,4,3] 00008 * Copyright 2007-2010 IMP Inventors.
