WebFeb 13, 2016 · 2. Below you will find a canonical, simple implementation of the Floyd-Warshall algorithm in CUDA. The CUDA code is accompanied with a sequential implementation and both are based on the simplifying assumption that the edges are non-negative. The full, minimum distance paths are also reconstructed in both the cases. WebRabin-Karp algorithm is an algorithm used for searching/matching patterns in the text using a hash function. Unlike Naive string matching algorithm, it does not travel through every character in the initial phase rather it filters the characters that do not match and then performs the comparison. A hash function is a tool to map a larger input ...
