For a long time I think the Dijkstra algorithm (dij) only has two usages: (1) Calculate the distance between vertices when the weights of edges are non-negative. (2) (Minimax) Given a path p=x1x2...xnp=x1x2...xn, define f(p):=maxn−1i=1d(xi,xi+1)f(p):=maxi=1n−1d...
I used dijkstra algorithm to solve it. I generally use the template from here, but in this question, this implementation gave me WA. When I used another implementation using visited array, it gave AC. WA code AC Code Naturally, I adopted the visited array approach and discarded the one ...

After analysis of classical Dijkstra's algorithm,the key factors that influence the efficiency are storage space and time efficiency.Some optimization strategies of the Dijkstra's shortest route algorithm are concluded by combination of some existing algorithms,which include optimization strategy of related...
On this basis, the Dijkstra algorithm model based on demand is further established. According to the linear relationship between demand and distribution distance, the optimal path selection model is established: $$ \theta = \sum {f\left( x \right)} \cdot w_{ij} $$ (12) Based on the ...
