Greedy pathfinding algorithm
WebOct 23, 2012 · It says A* is faster than using dijkstra and uses best-first-search to speed things up. A* is basically an informed variation of Dijkstra. A* is considered a "best first search" because it greedily chooses which vertex to explore next, according to the value of f (v) [ f (v) = h (v) + g (v)] - where h is the heuristic and g is the cost so far. A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in … See more Greedy algorithms produce good solutions on some mathematical problems, but not on others.
