No, the optimization problem is to speed up for a given set of parameters, one single expression involving log/exp, addition/subtraction/multiplication/division with huge numbers.
That';s all I need. Once the critical single expression has been optimized, then I can vary the parameters. The current focus is that single expression.

That's right. When reading Michael9;s messages, I always wonder why he insists on speeding up GMP and MPFR. I bet that GMP and MPFR are those parts of his software that already _are_ near the optimum run-time efficiency.
As you (Patrick) suggested, Michael should concentrate on speeding up the algorithm that makes use of MPFR. It sounds like his algorithm follows a brute-force approach of trying all possible combinations of values of some variables.
