摘要

A Uniform Generation procedure for NP is an algorithm which given any input in a fixed NP-language, outputs a uniformly distributed NP-witness for membership of the input in the language. We present a Uniform Generation procedure for NP that runs in probabilistic polynomial-time with an NP-oracle. This improves upon results of Jerrum, Valiant and Vazirani, which either require a 2P oracle or obtain only almost uniform generation. Our procedure utilizes ideas originating in the works of Sipser, Stockmeyer, and Jerrum, Valiant and Vazirani
