Hi, The number of failures is the standard measure used in CP: the number of times a failure is detected (i.e., the number of failed leaves in the tree). In the next version of Gecode we have added a counter for the number of nodes in the search tree in addition. If you want this information now for some problem, you can also run Gist.
