lib(gfd_search)


  This library provides the generic search facilities search/6, delete/5
  and indomain/2 for the GFD solver, compatible with the corresponding
  versions in library(fd_search) and library(ic).

  criteria (in addition to the generic ones) in delete/5 and search/6:

  max_regret_lwb
  max_regret_upb
  max_weighted_degree
  most_constrained_per_value
  max_weighted_degree_per_value
