Quiz on depth first search, non recursive DFS, branch and bound, breadth first search and best first search. A graph search is an algorithm for traversing or searching tree or graph data structures. It starts at the tree's root (or some arbitrary node of a graph, sometimes referred to as a 'search key'), and explores as far as possible along each branch before backtracking. Graph search algorithms are used to solve many problems in computer science, including: Finding the shortest path between two nodes in a graph Finding all the nodes in a graph that are connected to a given...

Graph search algorithms are used to solve many problems in computer science, including: Finding the shortest path between two nodes in a graph Finding all the nodes in a graph that are connected to a given node Finding the minimum spanning tree of a graph Finding the maximum flow through a network Finding the topological order of a directed acyclic graph There are two main types of graph search algorithms: Depth-first search (DFS): DFS explores as far as possible along each branch before backtracking. This can be useful for finding all the nodes in a graph that are connected to a given node, or for finding the shortest path between two nodes in a graph. Breadth-first search (BFS): BFS explores all the nodes at a given level before moving on to the next level. This can be useful for finding the minimum spanning tree of a graph, or for finding the maximum flow through a network. Both DFS and BFS can be implemented using a stack or a queue. A stack is used for DFS, while a queue is used for BFS. Related Test: Data Structures & Algorithms Practice Test: Graph Show less
