The project implements a Weighted and undirected graph model, using data structures including HashMaps to represent the nodes and neighborhood relationships between them.
This graph functions include:
- Saving the graph into a file
- Loading a graph from a file
- Find the shortest route between two nodes using Dijkstra's algorithm, implemented by a queue
- Returning the shortest path's between two nodes weight
- Adding and deleting nodes to a graph
- Add and delete neighbors to nodes in the graph
- Receiving the neighbors of a particular junction
- Adding information to the nodes themselves, in two information values ("variables") for each node
- Checking the connectivity of the graph
- Deep copy of the graph
Also, there are some RICH TESTS for you to test almost everything in there. Got any additions/ comments? I would love to hear.
Download the code and put it where you can access it. You can start creating a graph by the command WGraph_DS g = new Wgraph_DS <> (); Then add nodes using the g.addNode (new NodeInfo (your desired new node key)) command. Continue as you wish. The project is full of descriptions about the functions and their use.
