The evolved interrogation techniques developed by Ozma require large amounts of computing power and time, but the success of the process is inevitable. First, the ego to be interrogated is forked. Each fork is subjected to a series of stimuli; random variations on sets of stimuli that were successful in previous interrogations. Those sets of stimuli that provoke the most useful responses in the ego are used as the seeds for the next generation. The effect is to generate, through genetic algorithm, programs of torture, illusion, pleasure and other, stranger stimulations that will best prize information from an ego.
Plot Hook: The Ozma program has been running for so long, against so many egos that its methods are beginning to resemble primitive basilisk hacks. To fully pursue this line of research will require computing resources difficult even for Ozma to acquire. Firewall has become concerned with the sudden demand for computing power in the inner system, and tasks the players to investigate.
