[Scilab-users] fmincon won't work

["Stéphane Mottelet (UTC)"]

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.

Stéphane
