Alternatively called NP-C or NPC, NP-complete is a classification of problems in computer science. NP-complete problems are verified but not solved by a computer in a reasonable time. The “NP” stands for “non-deterministic polynomial time,” and refers how long it would take a computer to verify that the problem is solved.
For example, NP-complete problems are important in cryptography, where it is crucial to know if a password can be guessed given enough time trying random combination of letters and numbers.
