Search problems are challenges where the goal is to find a specific solution or item from a set of possibilities. These problems can occur in various fields, such as computer science, mathematics, and artificial intelligence. They often involve navigating through a space of potential solutions to identify the most suitable one. In computer science, search problems can be categorized into different types, such as unstructured search and structured search. Unstructured search involves exploring a large set of options without any specific order, while structured search uses algorithms to systematically narrow down choices. Common examples include pathfinding in graphs and database queries.
