The open-source algorithm that decides, every 5 minutes, how much insulin a pump should give, based on glucose readings and insulin already given. MIT licensed.Why it matters. It is the project Virtual Trial protects. Its logic was carried into other open-source dosing apps (AndroidAPS, Trio).Source running on Google Cloud, and shows the temporary basal rateTemporary basal rateWhat it is. A short-term change to the steady background insulin a pump gives, in units per hour, usually for 30 minutes. This is oref0's main lever.Why it matters. Small changes every 5 minutes are how the algorithm keeps glucose in range. it chooses for the next 30 minutes.

This shows a single decision. A trial repeats it every 5 simulated minutes for 14 days, for every virtual patient, under both the old and new code.
