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. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

% NTCC Oscillator Example
% Demonstrates Non-deterministic Timed Concurrent Constraints (NTCC)
% An oscillator process that alternates between high and low states each time unit
osc_high = tell(state = high) || next osc_low.
osc_low = tell(state = low) || next osc_high.
react =
when (state = high) do tell(output = 1) ||
unless (state = high) next tell(output = 0) ||
next react.
main = osc_high || react.
