Dijkstra’s … 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.
