Can the dijkstra algorithm calculate a minimum path for any cumulative function whose value can only increase or persist while iterating through the path? Say, we want to find a path from one vertex to all other vertex, whose bitwise-or of the weights is minimal. Can we use dijkstra in ...
[...] = graphshortestpath(..., 'Method', MethodValue, ...)lets you specify the algorithm used to find the shortest path. Choices are: [...] = graphshortestpath(..., 'Weights', WeightsValue, ...)lets you specify custom weights for the edges. WeightsValue is a column vector having...

Finding the shortest Hamiltonian Path in an undirected weighted graph can be found using Dijkstra's algorithm. The problem is NP-Complete because 3-CNF, a known problem in the NP- Complete class, is reducible to the Hamiltonian Path and a solution can be verified in polynomial time. This ...
Dijkstra’s algorithm can work on both directed and undirected graphs, but Prim’s algorithm only works on undirected graphs Prim’s algorithm can handle negative edge weights, but Dijkstra’s algorithm may fail to accurately compute distances if at least one negative edge weight exists ...

You are given a weighted undirected graph. The vertices are enumerated from 1 to n n n . Your task is to find the shortest path between the vertex 1 1 1 and the vertex n n n . 输入格式 The first line contains two integers n n n and m m m ( 2<=n<=105,0<=m<=105 2<=n...
A versatile implementation of Dijkstra's shortest path algorithm. Key features: No reliance on any particular graph representation. Requires only a function that returns a node's successors. Supports lazy graph descriptions, since nodes are only explored as required. Only a single dependency: gleamy...
