Dijkstra's algorithm allows one to find the shortest path from one vertex/node to another in a graph/network. For this assignment, we were tasked with implementing Dijkstra's algorithm and verifying its correctness on a given graph. The end product is something I'm quite proud of - an implementation utilizing the algorithm visualization. Dijkstra's algorithm does not support negative distances. The algorithm assumes that adding a relationship to a path can never make a path shorter, an invariant that would be violated with negative distances. Visualization By the way, I am not sure why you say you have to generate the segments manually - because the whole point of Dijkstra's algorithm is to find shortest paths in a graph, which (by definition) consists of nodes/vertices and segments/edges - so if you do not already have nodes and segments defined, it is unclear why you are trying to use this function at all

������ Dijkstra Algorithm Dijkstra's algorithm can be used to determine the shortest path from one node in a graph to every other node within the same graph data structure, provided that the nodes are reachable from the starting node. Dijkstra's algorithm can be used to find the shortest path. ������ A-star Algorithm The core idea of the Dijkstra algorithm is to continuously eliminate longer paths between the starting node and all possible destinations. To keep track of the process, we need to have two distinct sets of nodes, settled and unsettled. Settled nodes are the ones with a known minimum distance from the source
