[Scilab-users] Large scale linear optimization

[Claus Futtrup]

Hi Ashish Jaen

I of course cannot know about your problem explicitly, but I'd say that 
2000 values (variables) is no problem. I've worked with vectors up to 2 
million in size. Also the 5000 constraints, well, it sounds like it can 
be done.

There is a problem with Scilab in its current form having limits to 
managing memory. You should execute the command stacksize('max'); to use 
as much available memory as possible. I believe that Scilab is working 
on removing this limit in a future edition of Scilab (v. 6).

Whether you will run into a memory problem I can't say. I guess, the 
only way to find out is to try.

Best regards,
Claus
