WebFeb 15, 2024 · JGraphT is an open-source Java class library which not only provides us with various types of graphs but also many useful algorithms for solving most frequently encountered graph problems. In this article, we’ll see how to create different types of graphs and how convenient it is to use the provided utilities. 2. Maven Dependency WebDijkstra Algorithm is a graph algorithm for finding the shortest path from a source node to all other nodes in a graph (single source shortest path). It is a type of greedy algorithm. It only works on weighted graphs with positive weights. It has a time complexity of O (V^2) O(V 2) using the adjacency matrix representation of graph.
