SEARCH_MPI
Parallel Search for Integer so that F(J) = C

SEARCH_MPI is a Python script which searches integers between A and B for a value J such that F(J) = C, using the MPI parallel programming environment under MPI4PY.

For the particular example considered here, the solution will be F(1,674,924,981) = 45.
