Greedy best first search算法
WebBest First Search is a searching algorithm which works on a set of defined rules. It makes use of the concept of priority queues and heuristic search. The objective of this algorithm is to reach the goal state or final state from an initial state by the shortest route possible. ... The greedy chooses the next best option for short term in the ... WebFigure 3.9: A graph that is bad for greedy best-first search. Example 3.14. Consider the graph shown in Figure 3.9, drawn to scale, where the cost of an arc is its length. The aim is to find the shortest path from s to g. Suppose the Euclidean straight line distance to the goal g is used as the heuristic function.
