Webthe stronger claim that fhas a poly-size oblivious permutation branching program (denoted pbp) with width 5. In a pbp, any two consecutive levels of the program represent a permutation when ... Let F(a;b) return true if the execution of the branching program on its given input enters node aand eventually transitions to the node band return ... WebOct 20, 2024 · Every ordered permutation branching program is a regular branching program, but not conversely. A series of works has shown that the Impagliazzo–Nisan–Wigderson (INW) pseudorandom generator can be instantiated with smaller seed length for regular or permutation branching programs.
WebAbstract We consider a restricted class of width-3 branching programs where each column of nodes depends on a single variable, and the 0-edges and the 1-edges out of each … Web1Recall, a permutation branching program of length Land width whas states at each level, an accepting and rejecting state at the top level. Each level j Lhas two permutations ˙ j;0 and ˙ j;1 associated, and there is an input-selector function which determines the input read at each level. The program execution starts at state 1 of level 0.
WebWe emphasize that our de nition of permutation branching program only allows one accepting vertex. This assumption is crucial: a permutation branching program with … WebMay 31, 2005 · One motivation for investigating permutation branching programs is to study the fine structure of NC 1 . Specifically, to determine whether the class ACC (the …
WebWe present an explicit pseudorandom generator for oblivious, read-once, permutation branching pro-grams of constant width that can read their input bits in any order. The seed length is O(log2n), where n is the length of the branching program. The previous best seed length known for this model
