Not really answered in the paper... were those levels fun to play? The "Levels Evaluation" seemed a little lackluster too.
Back in early 2000 I ran a Quake server that generated levels that were decent. It would build a new one ever 15 minutes so when playing you would always find yourself in a new map regularly. I spent time tweaking it for fun and diversity which were the interesting bit. I didn't want to play the same level type over and over with guns just slightly shifted, but to play a wide range of experiences some of which were very surprising.
