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? ...
