Issue with non-negative variable tolerance.

[mariaepinheiro]

I am using IPOPT to solve an optimization problem.

One of my variables must satisfy 0 \leq x \leq 1. But the problem gives a solution of -1e-7, which cannot happen, Is it possible to put some command so that the tolerance of the feasible point is smaller (1e-9 for example)?

You can find the list of attributes here:
https://coin-or.github.io/Ipopt/OPTIONS.html#OPTIONS_REF
and you can set them with set_attributes as explained here:

Closing because this is not a bug in Ipopt.

If you have any questions related to Ipopt and tolerances, please post on the community forum, https://discourse.julialang.org/c/domain/opt/13, and we can discuss further.
