Single Source Shortest path (Dijkstra algorithm) PHP implementation to do a medical project, wherein the case score will be used in the single source shortest path algorithm. The idea of the Dijkstra algorithm for 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. So (Vi ... VK) must also be the shortest path from I to K. Dijkstra is an algorithm that increments the shortest path length and generates the shortest path successively. For example: for the source vertex V0, first select the shortest vertex vi in its directly adjacent vertex, then the shortest distance from V0 to the VJ Vertex is currently known dist[j]=min{dist[j],dist[i]+cost[i][j]}. Suppose g=, the source point is V0,u={v0} represents the set of vertices that have been marked, dist[i] records the shortest distance V0 to I, and cost[i][j] represents the cost of the edge I to J. 1. Select the vertex i with the lowest value of dist[i] from v-u, add I to U; 2. update with 1. Single-stream Shortest path (d
