WebThe bottleneck distance from s to t is deﬁned to be the smallest bottleneck path legnth among all paths from s to t. Describe an algorithm to compute the bottleneck shortest path distances from s to every node in G by adapting Dijkstra’s algorithm. Can you also do it via a reduction to the standard shortest path problem? Webeﬃciently solving path problems in graphs. We focus on several path problems optimizing diﬀerent measures: shortest paths, maximum bottleneck paths, minimum nondecreasing paths, and various extensions. For the all-pairs versions of these path problems we use an algebraic approach. We obtain improved algorithms using reduc-
