Improving backtracking efficiency

WitrynaFunctionally, this leads to an improvement in the backtracking efficiency because (1) there are fewer values in domains to explore, and (2) we have an early backtracking condition if a variable's domain is ever reduced to the empty set. Note that, in principle, after assigning to what variable could we have detected this inevitable conflict? ... Witryna11 paź 2010 · Improving backtracking efficiency • Previous improvements introduce heuristics • General-purpose methods can give huge gains in speed: • Which variable should be assigned next? • In what order should its values be tried? • Can we detect inevitable failure early? • Can we take advantage of problem structure?
