Permutation Problems and Channelling Constraints

WebMay 20, 2024 · We look at the problem of verifying permutation invariance in Deep Neural Networks (DNNs) – if certain permutations are applied on the inputs, its effect on the outputs will also be a permutation (possibly identity). These properties surface in many interesting practical applications of DNNs, e.g. consider the aircraft collision avoidance … 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 ...

From there, we can determine how … 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)
