I am wondering whether (and how) it is possible to use the least-squares
fitting, or alternatively minimization functions of gsl with constrained
parameters.  What I mean with this is that I want to force the function
into the correct local minimum by supplying information which parameter
values are physically meaningful for these particular data, or which of
two degenerate minima I would like (to be able to compare different
fits).  For example, if the function is the sum of two exponentials, I
would like to perform a least-squares fit to some data with the
constrain that the first of them has the shorter relaxation time.

Is this possible, and how would that be implemented?

TIA, Frank
