Solver

Solver was a slave profession on Poritrin.

While the usage of thinking machines and computers was prohibited, all serving Omnius, scientists such as Tio Holtzman made use of a large amount of slaves who performed complex mathematical equations, simulating thus a human-driven effect of a computer.

Behind the scenes
This profession actually existed in real word before the advance of informatics. It was called Human computer.
