Supports domain consistency (icl = ICL_DOM, default) and bounds consistency (icl = ICL_BND). GECODE_INT_EXPORT void GECODE_INT_EXPORT void Gecode::unshare (Home home, BoolVarArgs &x, IntConLevel icl=ICL_DEF) unshare Home home BoolVarArgs & x IntConLevel icl ICL_DEF Replace multiple variable occurences in x by fresh variables. Unsharing replaces multiple occurences of the same variable by fresh yet equal (enforced through propagators for equality) variables: after unsharing a variable appears at most once. Note that this is only done for not yet assigned variables (as all propagators can handle multiple occurences of the same variable provided it is already assigned).Unsharing is useful for constraints that only accept variable arrays without multiple occurences of the same variable, for example extensional.
