We now take a more detailed look at one of the top agents. R. 5210008 is at the time of this analysis, the top rated agent with an experience of more than 400 games; it has played 528 games and is the tenth ranked robot among those with 100 or more games played.
With its difficult structure, we were not able to manually de-compile the expression into pseudocode to try and follow the logic. The beginning of such pseudocode would be:
then
Then
else y = FRONT
then
The first inequality involves 4 different sensors in a complex relationship, including a confusing multiplication and is already difficult to understand; it may generate a right turn or not, in which case the evaluation continues. And this is just the first expression of a long program, which would take several pages of pseudocode. Instead we have manually looked at several games from our historic records -- to see how the agent behaves in the game environment.
So the next section, which talks about emergent behaviors in general, takes most of its examples from this player. We found out that it is capable of producing a surprising assortment of different behaviors including a different opening move for each game, cutting off the opponent , open box ``traps'' , driving around the edges and so on (figs. 3.31, 3.32, 3.33, 3.34 and 3.35).
