shortest-path

代码说明：

  dijkstra计算最短路径，算法在优化、图像处理、网格处理等相关领域有非常广泛的应用，希望能借此机会了解其实质内容，并灵活应用其到所学领域中。(dijkstra calculate the shortest path algorithm optimization, image processing, mesh processing and other related fields have a very wide range of applications, hoping to take this opportunity to learn about its substance, and the flexibility to apply their learning to the field.)
