Transitive reduction in parallel via branchings

Book ·
OSTI ID:6471860
The authors study the following problem: given a strongly connected digraph, find a minimal strongly connected spanning subgraph of it. Their main result is a parallel algorithm for this problem, which runs in polylog parallel time and uses O(n{sup 3}) processors on a PRAM. The authors' algorithm is simple and the major tool it uses is computing a minimum-weigh branching with zero-one weights. They also present sequential algorithms for the problem that run in time (m + n {center dot} log n).
