In computer science, A* (pronounced as “A star”) is a computer algorithm that is widely used in pathfinding and graph traversal, the process of plotting an efficiently directed path between multiple points, called “nodes”.It enjoys widespread use due to its performance and accuracy. However, in practical travel-routing systems, it is generally …

Depth First Search (DFS) searches deeper into the problem space. Breadth-first search always generates successor of the deepest unexpanded node. It uses last-in first-out stack for keeping the unexpanded nodes.

A* Algorithm. The A* algorithm combines features of uniform-cost search and pure heuristic search to efficiently compute optimal solutions. A* algorithm is a best-first search algorithm in which the cost associated with a node is f(n) = g(n) + h(n), where g(n) is the cost of the path from the initial state to node n and h(n) is the heuristic …

This research paper presents evidence from an exploratory survey on the use of agile project management (APM) practices and the presence of APM enablers in 19 medium- and large-sized companies from d…
