简介(Introduction) 迪杰斯特拉算法 $(Dijkstra\ Algorithm)$ 是由荷兰计算机科学家克斯特拉 1959年提出的。是从一个顶点到其余各顶点的 最短路径 算法,解决的是 有权图中最短路径问题。 迪杰斯特拉算法主要特点是从起始点开始,采用 贪心算法 的策略,每次遍历到始点
简介: GIS系列专题(4):使用贪心算法(Dijkstra Algorithm)解决最短路径问题(Calculating shortest path in QGIS) 1、最短路径问题介绍 问题解释: 从图中的某个顶点出发到达另外一个顶点的所经过的边的权重和最小的一条路径,称为最短路径。 解决问题的算法: 迪杰斯特拉算法(Dijkstra算法,即贪心算法) 弗洛伊德算法(...
