Dijkstra's greedy algorithm
WebFeb 25, 2024 · Dijkstra's algorithm is a greedy algorithm, the main goal of a Dijsktra's algorithm is to find the shortest path between two nodes of a weighted graph. Wikipedia does a great job with explaining what a deterministic and non-deterministic algorithms are and how you can 'determine' which algorithm would fall either either category: WebDijkstra's algorithm (/ ˈ d aɪ k s t r ə z / DYKE-strəz) is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, road networks. It was conceived by computer …

WebDijkstra’s algorithm, published in 1959 and named after its creator Dutch computer scientist Edsger Dijkstra, can be applied on a weighted graph. The graph can either be directed or undirected. One stipulation to using the algorithm is that the graph needs to have a nonnegative weight on every edge.
