迪杰斯特拉算法是由荷兰计算机科学家狄克斯特拉于1959 年提出的，因此又叫狄克斯特拉算法。是从一个顶点到其余各顶点的最短路径算法，解决的是有向图中最短路径问题。迪杰斯特拉算法主要特点是以起始点为中心向外层层扩展，直到扩展到终点为止。-Dijkstra algorithm is a Dutch computer scientist Dijkstra proposed in 1959, the so called Dijkstra algorithm. From one vertex to each vertex of the rest of the shortest path algorithm, the solution is a directed graph the shortest path problem. Dijkstra algorithm is the starting point for the center of the main features of the layers extend outward until extended to the end point.
