Reinforcement learning
In machine learning and optimal control, reinforcement learning (RL) is concerned with how an intelligent agent should take actions in a dynamic environment in order to maximize a reward signal.

System context
Reinforcement learningis aMachine learningEstablished
reinforcement learning is a kind of Machine learning.
Mechanism: Reinforcement learning is machine learning by trial and reward: an agent tries actions and learns the choices that earn the most reward over time.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 2 of 2 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Exercises 2 annotated mental models — a concept that connects several thinking patterns.
curated · Curated annotations, not a derived measure.
Structural neighbourhood: 1 → 20 → 128 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 1 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

Feedback loop
A loop where an effect feeds back to change its own cause. Reinforcing loops amplify change; balancing loops resist it.
Ask: does the result push the system further in the same direction, or pull it back?
Variation & selection
When many varying candidates are filtered by a criterion and the survivors are copied, the population adapts to the criterion over rounds — with no designer.
Look for three ingredients: variation, a selection pressure, and inheritance/copying. Together they design without a designer.
