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.
