Efficiently testing multiple primes at once

Read Original

This technical article examines an algorithm for testing multiple primes in a Cunningham chain of the second kind simultaneously, improving computational efficiency. It discusses the application of such prime chains in the Primecoin cryptocurrency as a proof-of-work task and provides code examples to demonstrate the algorithm's behavior and potential limitations, including the possibility of false negatives.
