  I'm not familiar with these works. Reading... [edit] Okay, I don't really understand what they're doing, so, my guess is that they have a component that predicts future states of the game, and they use something inspired by fractals to determine which future states to sample. Then, they're either using the score as the metric for the "value" of that future state (in which case it's not CEF), or they're ignoring the score and measuring something corresponding to entropy (or future-possibilies-remaining since it's pacman), and then they are using CEF. It's like Data playing that weird chess game; the CEF aspect doesn't help you play any better, but it gives you a different win condition that turns out to "win" better than directly trying to win. If, that is, my bad understanding is in any way accurate.
