Hello everyone,
it is true, I couldn't produce any meaningful results using /fmincon/ in
Scilab 5.4.1, while the module worked perfectly in the previous version
(Scilab 5-3.3).
However, running the nonlinear constrained optimization problem in
Scilab proved rather slow.
Scilab required the triple time for the solution of the program with
respect to Matlab.
At this point I should add that I was very careful to use the same
optimset in both Scilab and Matlab runs.
Does anyone have any experience in /fmincon/ time performance in Scilab?
PS. Stéphane, is the fsqp toolbox accessible to all Scilab users?
Thank you for your attention, Natasha

Hello,
Currently, sci_ipopt seems to be broken on Linux and MacOSX when using
the atoms package for Scilab 5.4.1. Since fmincon relies on sci_ipot,
fmicon is equally broken... BTW, users needing an optimization toolbox
with general non-linear constraints are not lucky with Scilab. As far
as I am concerned, I still use fsqp, which cannot be easily released
as an Atoms module because of proprietary code. But Ipopt is said to
really outperform fsqp, so I am rather impatient to see it coming.
As it is the only module of this class/kind (optimization +
complementary module), the Scilab team should take care of the
functionnality of it when new versions of Scilab are released.

Hello,
Did you check that your problem matched the cases described on
fmincon home page <http://atoms.scilab.org/toolboxes/fmincon>?

Paul

Hello everyone! I am a new Scilab 5.4.1 user (in Ubuntu 12.04.4).
I installed fmincon 0.3.1-1 using atoms, but when I tried it on the first
help example I obtained a rather weird output:
fval = 0.
x = 10^(-318) * Inf Inf
Could anyone help me please?
Thank you in advance, Natasha
