Dijkstra's algorithm java hashmap
WebDijkstra's algorithm is used to find the shortest distance between the nodes of a graph. We can use this algorithm for both directed and undirected graphs, but it won't work with negative edge weights. We can further optimize our implementation by using a min-heap or a priority queue to find the closest node. ← Java Type Casting WebAlgorithm 修改Dijsktra'；使用具有多个可能代价的边的s算法 algorithm graph 我需要使用Dijkstra算法的时间依赖变量，它可以处理从一个节点到另一个节点的两种可能方式，节点之间的成本（边缘成本）取决于我们到达源节点的时间和我们将要使用的边缘类型。
