Packages in Octave Forge (OF) can be installed from the command line in linux

(debian, ubuntu)
apt-get install octave-optim

or from your octave prompt
pkg install -forge optim

If you are in wiundoes, I know ther eis packages for that OS somewhere.

If I misundertood you and you have isntalled optim, please ignore my comments.
