GPU implementation of Floyd-Warshall and R-Kleene algorithms to solve the All-Pairs-Shortest-Paths(APSP) problem on Graphs. Code includes random graph generators and benchmarking/plotting scripts.
The Fast APSP algorithm is used to solve the All-Pairs Shortest Paths (APSP) problem. The algorithm uses the divide and conquers strategy. First, divide the graph structure by METIS, and divide the input graph G into multiple subgraphs. Then the solution of the APSP problem is solved by computing the subgraph. The Fast APSP algorithm combines th…
