Informed Search Strategies 启发式搜索是一种利用领域特定的提示(启发信息)来更高效地找到解决方案的方法。这些提示通常通过启发函数(heuristic function) h(n)表示,帮助算法估计从当前节点到目标节点的最小代价,从而减少搜索空间,加快搜索速度。 启发函数 h(n)的定义 估计路径成本: h(n)返回从节点 n 到达目标状态...
根据队列的实现方式(如先进先出、后进先出或优先队列),节点加入的顺序可能影响搜索路径的扩展顺序。 Uninformed Search Strategies Uninformed search vs Informed search 无信息搜索算法在问题定义之外没有额外的信息,也就是说,只有关于状态、初始状态、可能的操作、转换模型、目标测试和操作成本的基本信息。 特点: 无...
We assess our search approach by comparing it with other three recent search strategies of artificial intelligence, using a common source of articles from the Web of Science. Using this source, we then profile patterns of growth and international diffusion of scientific research in artificial ...
These alternate representations are based on generalizations of state-space and AND/OR graph models and search strategies developed in artificial intelligence (AI). The paper also briefly touches on other current interactions and differences between artificial intelligence and pattern recognition. 展开 ...
Query strategies are typically some mix of exploration (aiming to maximize new information) and exploitation (aiming to optimize a property). Show more AI for computational quantum materials In application after application, it has been demonstrated that ML can turn complex multidimensional data into ...

To be specific, these search strategies can be divided into at least three categories: reinforcement learning (RL), evolutionary algorithms (EAs), and gradient-based (GD) methods. In addition, a few additional methods, such as random search [30, 31], Bayesian optimization [32, 33] and ...

The first three search algorithms are very similar. They only vary in their strategies to select a node to expand after each step. If you are confused about why we expand a node after each step, please refer to the tree-search and graph-search principles at the start of this article. ...
Many ensemble feature selection strategies incorporate diversity as an objective in the search for the best collection of feature subsets. A number of ways are known to quantify diversity in ensembles of classifiers, and little research has been done about their appropriateness to ensemble feature ...
