+=======================================
+
+O-M1: Only one parent is obsolete
+---------------------------------
+
+XXX Simple case are probably as good as any `O-A` case. However special case are

+the other parent).
+
+O-M2: both parent are obsolete
+------------------------------
+
+XXX currently we evolve one after the other.
