启发式算法的节点扩展策略也是最优最先,但在评价是否为最优时加入了启发式函数(heuristic function)的概念。相较于盲目搜索,启发式搜索给了搜索过程一个朝着目标前进的趋势。其中最基础的就是A*算法和贪心算法。最直接的启发式信息就是欧几里得距离,或者曼哈顿距离。真正...
也就是说,该函数的IQ直接决定了寻找路径的快慢和准确度(accuracy) 在A*算法里: Evaluation function: f(n) = g(n) + h(n) h(n)就是启发函数,如果我们将该算法用于电脑在游戏中的角色,那么该函数将直接决定游戏地难度,当我们在调整游戏难度的时候,其实就是在重新选择一个更完美或者弱智的启发函数。 相关...

Let h(n) denote heuristic function and g(n) denote cost, the evaluation functionf(n) used by A* search is: 设h(n)表示启发式函数且g(n)表示代价,则A*搜索所使用的评价函数是: A.f(n) = h(n) B.f(n) = g(n) C.f(n) = g(n) + h(n) D.f(n) = g(n) - h(n) 相关知识...

The performance of heuristic search (such as A*) based planners depends heavily on the quality of the heuristic function used to focus the search. These algorithms work fast and generate high-quality solutions, even for high-dimensional problems, as long as they are given a well-designed heuris...
In computer science, a heuristic function is said to be admissible if it is no more than the lowest-cost path to the goal. In other words, a heuristic is admissible if it never overestimates the cost of reaching the goal. An admissible heuristic is also known as an optimistic heuristic....
