The P vs NP question in computer science investigates the relationship between problem-solving and solution verification complexities. It distinguishes between class P problems, solvable in polynomial time, and class NP problems, verifiable but not necessarily solvable in polynomial time. The text delves into the broad impact of this question on fields like cryptography, operations research, and drug discovery, illustrating the challenge with examples like Sudoku and the Travelling Salesman Problem. The historical context and future implications of solving this fundamental question are also discussed.
