Dear Paul,
Well, ok, if your problem is very large then algencan will use a lot of memory. However, if your problem is small, you can very easily solve it using algencan.
Just go to the file sources/algencan/dim.par and, with care, remove a couple of zeros from mmax, nmax, jcnnzmax, hnnzmax and nwma27.
The current version of dim.par looks like
C PARAMETERS
integer mmax,nmax,nsmax,nwma27,hnnzmax,jcnnzmax
parameter ( mmax = 500000 )
parameter ( nmax = 500000 )
parameter ( jcnnzmax = 10000000 )
parameter ( hnnzmax = 10000000 )
parameter ( nwma27 = 10000000 )
parameter ( nsmax = 1000 )
Your modified version should looks like
C PARAMETERS
integer mmax,nmax,nsmax,nwma27,hnnzmax,jcnnzmax
parameter ( mmax = 5000 )
parameter ( nmax = 5000 )
parameter ( jcnnzmax = 100000 )
parameter ( hnnzmax = 100000 )
parameter ( nwma27 = 100000 )
parameter ( nsmax = 1000 )
After doing this modification, compile and run again. Everything will work fine. (Fortran 77 has no dynamic memory allocation.)
Regards,
Ernesto.
