Patterns (YC S21) Is Hiring AI Engineers by cstanley | on Hacker News .

According to computational complexity theory, mathematical problems have different levels of difficulty in the context of their solvability. While a classical computer can solve some problems (P) in polynomial time—i.e., the time required for solving P is a polynomial function of the input size—it often fails to solve NP problems that scale exponentially with the problem size and thus cannot be solved in polynomial time. Classical computers based on semiconductor devices are, therefore, inadequate for solving sufficiently large NP problems. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/301PwUf
