NP-completeness

NP-completeness is a concept in computer science that describes the hardest problems in a group called NP. These problems are challenging because, while verifying a solution is quick, finding that solution in the first place can be very difficult and time-consuming. If a quick method were found to solve one NP-complete problem efficiently, it could potentially solve all problems in NP just as easily. This idea helps researchers understand the limits of what can be efficiently computed and guides efforts in problem-solving and algorithm development.
