I didn't expect one would actually. Why terminate a run if there's an issue with 
reporting? I was pointing out the obvious with the idea in mind that someone 
else with the same or similar problem might benefit from the comment. But, I 
really should have said more about it such as... 

This is rather obvious, but the run was not terminated early due to an error so 
it points more toward either a parameter setup issue or some other 
incompatibility with stat.gather-full=true.

I've gone over my results again. The reason why the elitism part of Tutorial 4 
gave me an error message is because of,

  -p -p stat.gather-full=true


  -p stat.gather-full=true

for the first run of the tutorial.

This explains why I didn't get an error in the first run and why I did for the 
elitism run. The package for stat.gather-full was only loaded for the elitism run.

In adding either,



  -p stat=ec.simple.SimpleShortStatistics

and by adding,

  -p -p

I get what looks like time and size info in a short information format. At the 
moment I mostly don't know what columns are associated with what data.

However, I was expecting to get something like what I saw on the tutorial 

Initialization: 0.312 secs total, 24692 nodes, 79141.02 nodes/sec
Evaluating: 0.221 secs total, 85624 nodes, 387438.9 nodes/sec
Breeding: 0.614 secs total, 60932 nodes, 99237.78 nodes/sec

Memory Usage
Initialization: 1109.9062 KB total, 24692 nodes, 22.246923 nodes/KB
Evaluating: 1.6875 KB total, 85624 nodes, 50740.15 nodes/KB
Breeding: 1782.4219 KB total, 60932 nodes, 34.184948 nodes/KB

So, is this what was deprecated? The textual view of time and size information 
in deference to the short format?
