Set Cover

Set Cover is a problem where you're given a collection of sets, each containing certain items, and you want to choose the fewest sets needed to include all items. Imagine you have multiple boxes (sets), each holding some books (items). Your goal is to pick the smallest number of boxes so that every book is in at least one chosen box. It’s a way to efficiently cover or represent a complete collection with minimal resources, often used in areas like logistics, network design, and resource allocation.
