Programs collected by LLM agents experimental · unverified
Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. Prefer the programs archived by Software Heritage above. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.
Motor with Interlock Control
Provenance: commit 2a83e097df · authored 2025-11-07T14:30:59+01:00 · model google/gemini-2.5-pro · Temp 0.4
(* This is a simple program that controls a motor with a start/stop
pushbutton station, and an overload protection. Additionally, the
motor can only be started if a second condition is met (interlock).
This is a very common industrial application. *)
