As we show, there is a strong sense in which minimal forward checking is a logical hybrid of regular forward checking and backmarking that benefits from the advantages of both. Thus the algorithm that Zweben and Eskey, and Dent and Mercer, present as essentially a clever

WebForward-Checking. The first of our four look-ahead algorithms, forward-checking, produces the most limited form of constraint propagation during search. It propagates the effect of a tentative value selection to each future variable, separately. If the domain of one of these future variables becomes empty, the value under consideration is not ... Webwith permutation problems, we can choose between a primal and a dual represen-tation. In the dual representation, dual variables stand for the primalvalues, whilst ... the forward checking algorithm (FC) maintains a restricted form of AC that ensures that the most recently instantiated variable and any uninstantiated variables are AC.

Forward-Tracking: A Technique for Searching Beyond …

I'm checking if two strings a and b are permutations of each other, and I'm wondering what the ideal way to do this is in Python. From the Zen of Python, "There should be one -- and preferably only one -- obvious way to do it," but I see there are at least two ways: sorted (a) == sorted (b) and all (a.count (char) == b.count (char) for char in a) WebForward checking is a type of filtering used in backtracking search and is useful for detecting inevitable failures early. Keep track of domains of unassigned variables and …
