Restricting solver to positive varriable values
TorkelE opened this issue · comments
I have a system of n function of n variables, and would like to find a solution to it. I know that there are several solutions, but am quite certain that there are only one for non-negative variable values (there is at least one such value).
Is there any good way to restrict the solver to not look for solutions with negative values?
Do you experience the iterates having negative values?
Yes, I give a strictly non negative initial value and find a solution for negative value. However, this might be due to me not providing a jacobian.
(I switched to using JuMP, a suggested possibility in the description, as it allows to restrict to non negative variable values)
There are some possibilities to enforce such constraints, but it's sadly not implemented yet.
Ok, good to know.
