Hi Noemie,

By experience, it is common to get spambase example to stall. The
problem is that this is an example of strongly-typed GP (STGP), and
that with a bad configuration, the typing can be never valid under
some circumstances. The STGP is implemented in version 2.2.0 with
brute-force, when some configuration is not feasible according to the
typing constraints, the program is sometime not able to figure it. In
these circumstances, it just try again and again, indefinitely.

If you don't want to do STGP, I would advice you to avoid it, given
these considerations. If you insist, I would advice you to look at the
sp-evolver.conf file, which is probably using parameters that are not
correct.

Best,

Christian
