Dear Stephane,

Thank you for offering these enhanced capabilities in Scilab, fmincon and SciIPOpt. I'm about giving a try in comparison with leastsq(), on dynamic model parameter (~5-10) calibration purpose, based on measurement deviation, as time series (250 to >1000 samples). In general for fmincon and SciIPOpt, may I provide the objective function with inputs argument through the list() syntax like objf=list(myofunction,x,in1,in2,..) ?

Thank you for your advice,

David

Objet?: [Scilab-users] fmincon toolbox update

Hi all,

I would like to inform you that the fmincon toolbox has been updated
(https://atoms.scilab.org/toolboxes/fmincon/1.0.2) and now includes a major feature:? the Efficient Computation of Sparse Hessian using Coloring algorithm (scicolpack is now a? dependency of fmincon). This feature was missing and now allows fmincon to consider really big problems. A example of such is given in the "minimal surface demo" which compares 3 different approaches of the problem: one with finite differences gradient, and BFGS Hessian, one with exact gradient and BFGS Hessian, and the last with exact gradient and finite differences sparse Hessian. The time factor between the first and the third approchach is around 200 for a 21x21 square but you can edit the demo file and increase this value. For a 51x51 square the third approach takes only
0.45 seconds and is 2500 times faster. For a 101x101 square the first approach takes forever and the third ones takes less than 2 seconds and is still 10 times faster than the second one.

If some of you still use other softwares for large scale optimization, maybe you can now give Scilab a try. If you need a better control on parameters and/or if you are not a former/actual user of Matlab's fmincon, I recommend using directly ipopt (from sci_ipopt toolbox). But the fmincon api is quite easy to use. Don't hesitate to took at the code of the several new demos.

Don't hesitate to contact me if you have some problems using fmincon of just to say that you are using it with success !

Regards,

Yes, you have such an example in the fitting demo ;

Hello St?phane

This seems very interesting, but download through Atoms does not work (at
least for me: I use Scilab 6.1.0 under Windows 10): dependencies
(Sci-colpac, Sci-IPOt, for those I have noticed) are not dealt with.
Moreover, trying to install Sci-IPOt with Atoms fails. By the way it makes
also make fail lthe oading of  any module that could have been installed
with Atoms, which reveals an undesirable feature of Atoms: failure to load
a module should not prevent the loading of other ones.

Best regards,

?ric

Hi Eric, 

Could you be more precise ? I have I installed fmincon on at least 10 different machines for testing purposes  (mostly under Windows 10) and did not encounter any problem. Atoms is, I must say, a very unstable (not to say crappy) piece of software and in particular very hard to use smoothly when your are developing some modules and play e.g. with offline mode. 

What I would do first is to uninstall every module then install fmincon. If problem is still here please help me by debugging a bit...

Thanks St?phane for your quick answer

I have tried installing fmincon first, then scicolpack (it works), then
sci_ipopt  and it does not work: only
file sci_ipopt_1.3.bin.x64.Windows.zipis downloaded. So it seems:
- first that dependencies are not deal with for the fmincon distribution
that Atoms uses;
- second, that there is some problem using Atoms for loading  sci_ipopt

Maybe I should not use Atoms, but when it works it is the most convenient
way to download a module.

Hi all,

I installed both SciPOpt and fmincon from ATOMS on Scilab 6.1.0 WIN10-64bits, a few weeks ago and the demos are running properly. I had some minor dependencies issues while installing, I don?t remember exactly , probably the SciIPopt version was not aligned with the one required by fmincon.
My 2 cents

David

Hi Eric,

Could you be more precise ? I have I installed fmincon on at least 10 different machines for testing purposes  (mostly under Windows 10) and did not encounter any problem. Atoms is, I must say, a very unstable (not to say crappy) piece of software and in particular very hard to use smoothly when your are developing some modules and play e.g. with offline mode.

What I would do first is to uninstall every module then install fmincon. If problem is still here please help me by debugging a bit...

Hello St?phane

This seems very interesting, but download through Atoms does not work (at least for me: I use Scilab 6.1.0 under Windows 10): dependencies (Sci-colpac, Sci-IPOt, for those I have noticed) are not dealt with. Moreover, trying to install Sci-IPOt with Atoms fails. By the way it makes also make fail lthe oading of  any module that could have been installed with Atoms, which reveals an undesirable feature of Atoms: failure to load a module should not prevent the loading of other ones.

Best regards,

?ric

Yes, you have such an example in the fitting demo ;

This feature was missing and now allows fmincon to consider really big problems.

The time factor between the first and the third approchach is around 200 for a 21x21 square but you can edit the demo file and increase this value. For a 51x51 square the third approach takes only

If you need a better control on parameters and/or if you are not a former/actual user of Matlab's fmincon, I recommend using directly ipopt (from sci_ipopt toolbox). But the fmincon api is quite easy to use. Don't hesitate to took at the code of the several new demos.

Yes, there were successive versions of? sci_ipot over a short period, 
and since the updates only pop in the atoms gui (not at loading time), 
you can easily miss them. However, the situation is stable since the end 
of april and I don't plan a new release until the end of 2021.

Hi,

Yes I have successfully installed sci_ipopt and fmincon on Windows (but not using atoms).

Hello all,

I try to install to check fmincon to check on my machine and give you a fresh eye on the basic install/usage. I have a few remarks:


  1.  My Scilab and all atoms packages are installed in user directories but the library check at startup on sci_ipopt ask for administrator access to update. That?s a pity to require that.
  2.  The message ?This program contains Ipopt, a library for large-scale nonlinear optimization.? looks strange to me, this function is named ipopt and I think the references are written in the documentation and on the DESCRIPTION file. There is no need to display that at runtime.

Otherwise basic examples are running even if it change the toolbox loading order (sci_ipopt after fmincon, scicolpack after sci_ipopt, etc?).

Hi all,

I installed both SciPOpt and fmincon from ATOMS on Scilab 6.1.0 WIN10-64bits, a few weeks ago and the demos are running properly. I had some minor dependencies issues while installing, I don?t remember exactly , probably the SciIPopt version was not aligned with the one required by fmincon.
My 2 cents

David

May I ask if there are there some Windows users who read this post and who successfully installed sci_ipopt or fmincon ?

Thanks St?phane for your quick answer

I have tried installing fmincon first, then scicolpack (it works), then sci_ipopt  and it does not work: only file sci_ipopt_1.3.bin.x64.Windows.zipis downloaded. So it seems:
- first that dependencies are not deal with for the fmincon distribution that Atoms uses;
- second, that there is some problem using Atoms for loading  sci_ipopt

Maybe I should not use Atoms, but when it works it is the most convenient way to download a module.

Hi Eric,

Could you be more precise ? I have I installed fmincon on at least 10 different machines for testing purposes  (mostly under Windows 10) and did not encounter any problem. Atoms is, I must say, a very unstable (not to say crappy) piece of software and in particular very hard to use smoothly when your are developing some modules and play e.g. with offline mode.

What I would do first is to uninstall every module then install fmincon. If problem is still here please help me by debugging a bit...

Hello St?phane

This seems very interesting, but download through Atoms does not work (at least for me: I use Scilab 6.1.0 under Windows 10): dependencies (Sci-colpac, Sci-IPOt, for those I have noticed) are not dealt with. Moreover, trying to install Sci-IPOt with Atoms fails. By the way it makes also make fail lthe oading of  any module that could have been installed with Atoms, which reveals an undesirable feature of Atoms: failure to load a module should not prevent the loading of other ones.

Best regards,

?ric

I'm about giving a try in comparison with leastsq(), on dynamic model parameter (~5-10) calibration purpose, based on measurement deviation, as time series (250 to >1000 samples). In general for fmincon and SciIPOpt, may I provide the objective function with inputs argument through the list() syntax like objf=list(myofunction,x,in1,in2,..) ?

Yes, you have such an example in the fitting demo ;

This feature was missing and now allows fmincon to consider really big problems. A example of such is given in the "minimal surface demo" which compares 3 different approaches of the problem: one with finite differences gradient, and BFGS Hessian, one with exact gradient and BFGS Hessian, and the last with exact gradient and finite differences sparse Hessian. The time factor between the first and the third approchach is around 200 for a 21x21 square but you can edit the demo file and increase this value. For a 51x51 square the third approach takes only
> 0.45 seconds and is 2500 times faster. For a 101x101 square the first approach takes forever and the third ones takes less than 2 seconds and is still 10 times faster than the second one.

If you need a better control on parameters and/or if you are not a former/actual user of Matlab's fmincon, I recommend using directly ipopt (from sci_ipopt toolbox). But the fmincon api is quite easy to use. Don't hesitate to took at the code of the several new demos.

Do you mean that you manually open the packages zip file and exec the 
loader script manually for apifun, scicolpack, sci_ipopt and fmincon ?

The problematic library (shipped with official Scilab) (intel fortran 
lib) is very, very outdated. It hope it will be upgraded in Scilab 
6.1.1.. If you have a better way of upgrading it just tell me...

This is an advertising feature of IPopt and I don't know how to suppress 
it. It occurs only at first call of IPopt and was already present in 
original releases of sci_ipopt (Yann Collette was the maintainer)

Ok thanks for testing.

apifun is in fact loaded through atoms.
fmincon and sci_ipopt are loaded manually (exec(xxx..sce)) using the binary zip files.
(I have just run some examples so far)

Hi,

These problems are now? fixed in version 1.3.1. For the Windows version, 
if the update of libifcoremd.dll is necessary, the writeability of 
SCI/bin is tested in order to run the update script with admin rights 
only if needed.

Hi,

These problems are now  fixed in version 1.3.1. For the Windows version, if the update of libifcoremd.dll is necessary, the writeability of SCI/bin is tested in order to run the update script with admin rights only if needed.

Hello all,

I try to install to check fmincon to check on my machine and give you a fresh eye on the basic install/usage. I have a few remarks:


1.      My Scilab and all atoms packages are installed in user directories but the library check at startup on sci_ipopt ask for administrator access to update. That?s a pity to require that.

2.      The message ?This program contains Ipopt, a library for large-scale nonlinear optimization.? looks strange to me, this function is named ipopt and I think the references are written in the documentation and on the DESCRIPTION file. There is no need to display that at runtime.

Otherwise basic examples are running even if it change the toolbox loading order (sci_ipopt after fmincon, scicolpack after sci_ipopt, etc?).

Hi all,

I installed both SciPOpt and fmincon from ATOMS on Scilab 6.1.0 WIN10-64bits, a few weeks ago and the demos are running properly. I had some minor dependencies issues while installing, I don?t remember exactly , probably the SciIPopt version was not aligned with the one required by fmincon.
My 2 cents

May I ask if there are there some Windows users who read this post and who successfully installed sci_ipopt or fmincon ?

Thanks St?phane for your quick answer

I have tried installing fmincon first, then scicolpack (it works), then sci_ipopt  and it does not work: only file sci_ipopt_1.3.bin.x64.Windows.zipis downloaded. So it seems:
- first that dependencies are not deal with for the fmincon distribution that Atoms uses;
- second, that there is some problem using Atoms for loading  sci_ipopt

Maybe I should not use Atoms, but when it works it is the most convenient way to download a module.

Hi Eric,

Could you be more precise ? I have I installed fmincon on at least 10 different machines for testing purposes  (mostly under Windows 10) and did not encounter any problem. Atoms is, I must say, a very unstable (not to say crappy) piece of software and in particular very hard to use smoothly when your are developing some modules and play e.g. with offline mode.

What I would do first is to uninstall every module then install fmincon. If problem is still here please help me by debugging a bit...

Hello St?phane

This seems very interesting, but download through Atoms does not work (at least for me: I use Scilab 6.1.0 under Windows 10): dependencies (Sci-colpac, Sci-IPOt, for those I have noticed) are not dealt with. Moreover, trying to install Sci-IPOt with Atoms fails. By the way it makes also make fail lthe oading of  any module that could have been installed with Atoms, which reveals an undesirable feature of Atoms: failure to load a module should not prevent the loading of other ones.

Best regards,

?ric

I'm about giving a try in comparison with leastsq(), on dynamic model parameter (~5-10) calibration purpose, based on measurement deviation, as time series (250 to >1000 samples). In general for fmincon and SciIPOpt, may I provide the objective function with inputs argument through the list() syntax like objf=list(myofunction,x,in1,in2,..) ?

Yes, you have such an example in the fitting demo ;

This feature was missing and now allows fmincon to consider really big problems. A example of such is given in the "minimal surface demo" which compares 3 different approaches of the problem: one with finite differences gradient, and BFGS Hessian, one with exact gradient and BFGS Hessian, and the last with exact gradient and finite differences sparse Hessian. The time factor between the first and the third approchach is around 200 for a 21x21 square but you can edit the demo file and increase this value. For a 51x51 square the third approach takes only
> 0.45 seconds and is 2500 times faster. For a 101x101 square the first approach takes forever and the third ones takes less than 2 seconds and is still 10 times faster than the second one.

If you need a better control on parameters and/or if you are not a former/actual user of Matlab's fmincon, I recommend using directly ipopt (from sci_ipopt toolbox). But the fmincon api is quite easy to use. Don't hesitate to took at the code of the several new demos.

Message-ID: <90dcc221-c893-a940-9951-8b3edf7be454@fceia.unr.edu.ar>

Dear all,

I try to save a signal as a wave file, using wavwrite(), to the root 
directory of the drive where I have declared the default directory. 
Unexpectedly, the wave file is saved to the default directory. For instance:

My default directory:

D:\work_scilab

My command:

wavwrite(x, Fs, "D:\test.wav")

The resulting path to my file:

D:\work_scilab\test.wav

instead of

D:\test.wav

I wonder if I making some mistake.

Thank you.

Regards,

Federico Miyara

Fine. So,? with "all your Scilab windows" are you addressing the 
console, the help browser, the file browser, xcos windows, etc ?
Or GUIs based on figures like the ATOMS GUI, the demos GUI, etc?

Hello,
yes, and to get the useful part of the window a little higher. The same 
without toolbars (that I never use).

Isn't there a text-file with window settings somewhere?

In the console menu I can choose to hide the toolbar but it is not 
remembered

Stefan

The console can be managed by the user through its handle and the 
visibility of the toolbar can be managed:

c = get(0);
c.toolbar_visible = "off";
