Let G denote an interval graph with n vertices and unit weight edges. In this paper, we present a simple O(n') algorithm for solving the all-pairs shortest path problem on graph G . A recent algorithm for this problem has the same time-complexity but is fairly complicated to describe. However, our a
We present a simple parallel algorithm for the single-source shortest path problem in planar digraphs with nonnegative real edge weights. The algorithm runs on the EREW PRAM model of parallel computation in O((n 2= +n 1&= ) log n) time, performing O(n 1+= log n) work for any 0<=<1ร2. The strength of
