爬山算法实现教学 在机器学习和优化问题中,爬山算法(Hill Climbing Algorithm)是一种简单而有效的启发式搜索方法。其主要思想是从当前状态出发,不断选择一个能够提高目标函数的邻居状态,直到无法找到更好的邻居为止。接下来,我将带你一步步实现一个简单的爬山算法,使用Python语言。 实现流程 以下是我们实现爬山算法的完...
爬山法(Hill Climbing,HC)是一种局部择优的贪心搜索算法,其本质上是梯度下降法。 该算法每次从当前的节点开始,与周围的邻接点进行比较: 若当前节点是最大的,那么返回当前节点,作为最大值 若当前节点是最小的,就用最高的邻接点替换当前节点,从而实现向山峰的高处攀爬的目的 如此循环往复,直到达到最高点为止。 但...

These algorithms can be visualized as blind hill climbing: we begin the search at a random point on the landscape, and then, by jumps or steps, we keep moving our guess uphill, until we reach the top. This process is called stochastic gradient descent.[71]\nEvolutionary computation uses a...
