Dear

It's a pity since the article is not available to "ordinary people"  ... and it seems to be rather interesting.

Dear Dr Reinaldo,

An overview of optimization in Scilab is done in :

"Optimization with Scilab, present and future", M. Baudin, S. Steer, 
2009 IEEE International Workshop on Open-source Software for Scientific 
Computation (OSSC).

which is available at :

http://ieeexplore.ieee.org/search/searchresult.jsp?newsearch=true&queryText=Optimization+with+Scilab%2C+present+and+future&x=0&y=0

The following is the abstract of the paper :

"We present in this paper an overview of optimization algorithms 
available in theScilab software. We focus on the user's point of view, 
that is, we have to minimize or maximize an objective function and must 
find a solver suitable for the problem. The aim of this paper is to give 
a simple but accurate view of what problems can be solved by Scilab and 
what behavior can be expected for those solvers. For each solver, we 
analyze the type of problems that it can solve as well as its advantages 
and limitations. In order to compare the respective performances of the 
algorithms, we use the CUTEr library, which is available in Scilab. 
Numerical experiments are presented, which indicates that there is no 
cure-for-all solvers."

The flagship of Scilab in terms of general nonlinear optimization
is currently the optim function, which allows to perform
unconstrained and bound constrained optimization.
It is shortly presented at :

http://wiki.scilab.org/The_optim_primitive

and in the help of Scilab :

You may get an overview of optimization features by
browing the help of Scilab :

What kind of optimization do you plan to do ?

If you are interested in a general overview of Scilab, you may
consider the "Introduction to Scilab" :

http://www.scilab.org/en/content/download/1104/10840/file/introscilab.pdf

Scilab provides its own language, but you can connect it to
C, C++ and Java. For example, in order to connect your
C or C++ library to Scilab, you can use the Scilab API :

http://www.scilab.org/product/man/section_204636e951f595409bc6782bb8e1d2d9.html

Many examples are provided in the libraries which are already connected
inside Scilab.

Best regards,

Michaël Baudin
