σ_odd problem

C++ (and OpenCL) implementations of sequential and parallel algorithms to check the σ_odd (sigma_odd) problem by the equivalent ς_odd (varsigma_odd) problem. Those are simple arithmetic conjectures like the iterative 3n+1 problem (Collatz conjecture), but they iterate a variant of the divisor function.

All results, documents, C++/OpenCL and LaTeX sources are available on Bitbucket: https://bitbucket.org/OPiMedia/parallel-sigma_odd-problem
