Recently, I was solving the Graphs section of the CSES problemset and encountered this problem. 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...
When understood in this way, it is clear how the algorithm necessarily finds the shortest path. However, it may also reveal one of the algorithm's weaknesses: its relative slowness in some topologies. About Implementation of Dijkstra's algorithm on C++ with reading a map from a file ...
By designing a suitable SuccessorsFunc function, and taking advantage of function captures and the variable node_id type, you can apply Dijkstra's algorithm to scenarios that would otherwise be difficult to model as a graph. In my experience, the most difficult part of applying Dijkstra from a...

In terms of Dijkstra's algorithm, this is what we actually do: We've got two groups of spheres - the ones on the ground and the ones that have already been lifted. In each iteration, we pick up one of the spheres from the ground and calculate their distance from the first...
It allows to implement an algorithm similar to the Dijkstra's one in order to solve the shortest path problem on a weighted graph. With this neural and parallel implementation, the presented model is adapted to possible modifications in the graph. Moreover, it is possible to solve other ...
