In this chapter, we explain why optimizing PHP involves many factors which are not code related, and why tuning PHP requires an understanding of how PHP performs in relation to all the other subsystems on your server, and then identifying bottlenecks caused by these subsystems and fixing them.

The bots sketch out odd patterns with their orders, leaving patterns in the data that are largely invisible to market participants.

Both various maze (spanning tree) algorithms and cellular automata have been applied for generating dungeons in roguelikes.
