WebJan 8, 2024 · As a compromise you can use data structures, that perform both types of operations (extracting a minimum and updating an item) in O ( log n) . Then the complexity of Dijkstra's algorithm is O ( n log n + m log n) = O ( m log n) . C++ provides two such data structures: set and priority_queue . The first is based on red-black trees, and the ... WebJul 30, 2024 · Algorithm: Begin function dijkstra () to find minimum distance: 1) Create a set Set that keeps track of vertices included in shortest path tree, Initially, the set is empty. 2) A distance value is assigned to all vertices in the input graph. Initialize all distance values as INFINITE. Distance value is assigned as 0 for the source vertex so ... red pepper atlanta
