WebMar 10, 2024 · Algorithm. 1) Create a set sptSet (shortest path tree set) that keeps track of vertices included in shortest path tree, i.e., whose minimum distance from source is calculated and finalized. Initially, this set is empty. 2) Assign a distance value to all vertices in the input graph. Initialize all distance values as INFINITE. WebSep 21, 2012 · The idea behind the algorithm is to run Dijkstra's algorithm with a twist. Normally, when running Dijkstra's algorithm, you keep track of the length of the shortest path to each node. In the modified Dijkstra's algorithm, you instead store, for each node, the maximum possible value of a minimum-weight edge on any path that reaches the node. stardew valley luck buff
