MMP.8.SD:3 - Forces
| Force | Tension |
|---|
| Useful memory | A compact state saves work, but merging histories can remove an allowed action or change its consequences. |
| Information timing | Later observations support conditional action, while a plan chosen now cannot depend on their unrealized values. |
| Present and later consequences | A locally attractive move may consume a resource, remove an option or change what can be learned. |
| Criterion choice | Expected total gain, probability of meeting a target and worst possible loss can prefer different policies. |
| Affordable adequacy | Exact reconstruction of the hidden state may be unnecessary; an adequate comparison or bound can already settle the use. |
| Model and computation | A correct solver can answer a deficient model, and an adequate model can remain computationally difficult. |
