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.)
