WebJun 24, 2011 · Objectively, this is an unsolved problem. There is no known way to implement a competitively-efficient pure Sieve of Eratosthenes. You can optimize it a bit but you will never approach the performance of an imperative solution, so it is an academic exercise. If you want to write fast code to solve these kinds of problems, you must embrace impurity. WebMar 9, 2024 · 2. So yet another Sieve of Eratosthenes in Python 3.
