WebNov 8, 2024 · Uniform-Cost Search vs. Best-First Search. 1. Introduction. In this tutorial, we’ll present and compare two search algorithms. Those are Uniform-Cost Search (UCS) and Best-First Search. 2. Search. In a search problem, we want to find the shortest sequence of actions that transform the start state to a goal state. A state can be anything. WebThe quality search is obtained by using the user profile built by using user’s history and searches.
