O que (quem) é graph search algorithm - definição

CHECKING AND/OR CHANGING EACH VERTEX IN A GRAPH
Graph exploration algorithm; Graph search algorithm; Graph search; Node traversal
  • A non-verbal description of three graph traversal algorithms: randomly, depth-first search, and breadth-first search.

Graph traversal         
In computer science, graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph. Such traversals are classified by the order in which the vertices are visited.
A* search algorithm         
  • The A* algorithm finding a path of railroads between Washington, D.C. and Los Angeles.
  • Illustration of A* search for finding a path between two points on a graph. From left to right, a heuristic that prefers points closer to the goal is used increasingly.
  • An example of A* algorithm in action (nodes are cities connected with roads, h(x) is the straight-line distance to the target point) Green: Start, Blue: Target, Orange: Visited
  • A* pathfinding algorithm navigating around a randomly-generated maze
  • A* was invented by researchers working on Shakey the Robot's path planning.
ALGORITHM USED FOR PATHFINDING AND GRAPH TRAVERSAL
A Star Search Algorithm; A star search algorithm; A-star algorithm; A-star search algorithm; A* algorithm; A* search; A-star; A Star; A star search; TBA*; New Bidirectional A*
A* (pronounced "A-star") is a graph traversal and path search algorithm, which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. One major practical drawback is its O(b^d) space complexity, as it stores all generated nodes in memory.

<algorithm> A graph search algorithm. A* is guaranteed to find a minimal solution path before any other solution paths, if a solution exists, in other words, it is an "admissible" search algorithm. Each path is assigned a value based on the cost of the path (e.g. its length) and an (under)estimate of the cost of completing the path, i.e. the cost of a path from the end of the current path to a solution.

Graph traversal

In computer science, graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph. Such traversals are classified by the order in which the vertices are visited. Tree traversal is a special case of graph traversal.
