That's because the tutorial example does not implement the describe() method.  But all the stats are outputted.

I do note one oddity with the statistics you provided: though the system finds a solution that has a standardized fitness of 0.0, it's not the best individual of run!  This is for two reasons:

- Floating point error results in the both 0.0 and 1.6653345E-16 getting converted to an adjusted fitness of 1.0

- Comparison is done based on adjusted fitness; but determination of ideal individuals is done based on standardized fitness. [ In a perfect world, with no floating point error, this wouldn't be an issue]

So I think we should move the GP comparisons to be entirely based on standardized fitness.  Or alternatively swich to doubles.  Or both.
