WebThis is the easiest way to implement Dijkstra's algorithm. The time complexity is O (V^2). Priority-queue/heap based implementation + NO re-entrance allowed, where re-entrance means a relaxed vertex can be pushed into the priority-queue again to be relaxed again later. Priority-queue/heap based implementation + re-entrance allowed. WebApr 24, 2014 · Idea #1: Find the enclosing polygon.

The problem can be solved using standard Dijkstra algorithm with slight modifications. In priority queue for each vertex a vector corresponding to {cost, time, vertex} is stored. The priority queue will be a min-heap, the vectors will be arranged first by cost and then by time. Source vertex (0) will be push into min-heap first.
