Hello, An eay-fast question: Is there any possibility to use "search/6" with the "backtrack(-N)" option in order to get the number of backtracks performed during the search not only when it is successful but also when the search fails? (When it fails, the variable N stays nonground). I know I can do it by programming my own labelling, but don't know if it is possible with the search/6 predicate. Thank you very much. Yours sincerely, Daniel -- "pluralitas non est ponenda sine neccesitate" (William of Ockham) http://requetenacimiento.blogspot.com/Received on Wed Sep 02 2009 - 07:17:18 CEST
