Many graph algorithms rely on efficient and systematic traversals of vertices and edges in the graph. The two simplest and most commonly used traversal methods are breadth-first search and depth-first search, which form the basis for many graph algorithms. We will examine their generic structures ...

Using theHAS_ROADrelationships and the distance for these relationships, we can see that the shortest drive will be to start in Springfield, then go to Cliffside, then to Newtown, and finally arrive in Centerville. More complex shortest path algorithms (for example, Dijkstra’s algorithm or A*...
This project builds a Java GUI application with Swing to create graphs and visualize graph algorithms like traversals, spanning trees, and shortest pathfindings.The user can add and remove vertices and edges by switching between the different modes present in the Mode menu item. After a graph ...
The following image shows the graph traversals in which breadth-first search is compared to depth-first search: Connected versus disconnected Last but not least is the notion of connectivity or a connected graph. In the next diagram, it is always possible to go from one vertex to another, ...

In in-order DFS, a node is processed between the traversal of its left and right subtrees. In other words, the left subtree is explored first, followed by processing the current node and then exploring the right subtree. In-order DFS is primarily used in binary tree traversals and is espe...
