TreeTransitionTypeII[tree1, tree2] returns the transition type. If tree1=tree2, returns {"0",0,0}. If the distance is greater than 2, returns {"-1", -1,-1}. Otherwise the distance d = 1 or 2 , returns {"groupid", d, {ops1, ops2, .. ..}}, where each groups of operators (denoted as ops1,...) produce same tree from tree1 by the mSMC transition, and operators from difference groups produce different tree. If d=1, the resulting tree is tree2, and if d=2, the resulting tree is an intermediate tree. |
