Can genetic algorithms break up the confine of local States?
However, the value assignments of their neighbors confine their search to a small space so that agents in local search algorithms easily fall into local optima. Fortunately, Genetic Algorithms (GAs) can direct a search process to a more promising space and help the search process to break up the confine of local states.

Let me start from the second question. I believe that there is no way to determine a better algorithm for a given problem without any trials and tests. The behavior of an algorithm heavily depends on problem's properties. If we are talking about complex problems with hundreds and thousands of variables, it's just too difficult to predict anything. I'm not talking about your engineer's intuition, some deep problem understanding, previous experience, etc, they are not really measurable.

Search algorithms
Which search algorithms are used to solve different tasks?For example, route finding, robot motion planning and machine translation. In this article, we will delve into several common search algorithms and see how they are used to solve different tasks. The rest of the article will cover BFS, DFS, IDDFS, Dynamic Programming, Dijkstra’s Algorithm and A*.

How complex is a search algorithm?Searching can have different levels of complexity depending on the data structure and the algorithm used. The complexity is often measured in terms of time and space requirements. Some searching algorithms, like binary search, are deterministic, meaning they follow a clear, systematic approach.
