Single source shortest path (dijkstra algorithm) PHP implementation for a medical project, in which the single source shortest path algorithm will be used in case scoring. The idea of ​​​​the dijkstra algorithm for the single-source shortest path is as follows: If there is a shortest path from i to j (Vi...Vk, Vj), Vk is a vertex in front of Vj. Then (Vi...Vk) must also be the shortest path from i to k. Dijkstra is an algorithm that successively generates the shortest path with increasing length of the shortest path. For example: for the source vertex V0, first select the vertex Vi with the shortest length among its directly adjacent vertices, then it is currently known that the shortest distance from V0 to the Vj vertex dist[j]=min{dist[j],dist[ i]+cost[i][j]}. Assume G=, the source point is V0, U={V0} represents the set of marked vertices, dist[i] records the shortest distance from V0 to i, and cost[i][j] represents the cost of edge i to j. 1. Select the vertex i that minimizes dist[i] value from V-U, and add i to U; 2. Update and

1. Single flow shortest path (dijkstra algorithm) PHP implementation

Introduction: Single source shortest path (dijkstra algorithm) PHP implementation to do a medical project, in which single source will be used in case scoring Shortest path algorithm. The idea of ​​​​the dijkstra algorithm for the single-source shortest path is as follows: If there is a shortest path from i to j (Vi...Vk, Vj), Vk is a vertex in front of Vj. Then (Vi...Vk) must also be the shortest path from i to k. Dijkstra is an algorithm that successively generates the shortest path with increasing length of the shortest path. For example: for

2. Graph (2)

## Introduction: 1: Graph traversal 1. Concept: Starting from a certain vertex in the graph, the remaining vertices in the graph are visited, and each vertex is visited only once (the graph traversal algorithm is the basis for algorithms such as solving graph connectivity problems, topological sorting, and finding critical paths.

4. Photoshop to create a gray sun hat

Introduction: The production process of this tutorial is relatively simple. Basically, you use the pen tool to outline the shape and then add the gradient color. However, the seemingly simple hat also has many light-receiving surfaces, so you must pay attention to the overall light sensitivity.
