Riesel Prime Search (RPS) is a prime search project established in 2005 by Predrag Minovic (Kosmaj).

The project description is as follows:

The project is searching for Riesel primes k•2n-1, k > 1.
There are three subprojects as follows:
  1. High-weight k-values that can produce many primes in a given range of exponent n.
  2. Low-weight k-values that produce a very small number of primes, opposite to #1 above.
  3. Small k < 300 with the exception of k-values already reserved by other projects.
