Knowledge Checks

Knowledge checks appear inside the concept and research pages at the point where a prediction or interpretation matters. They are short, specific to the idea just developed, and provide immediate feedback for every option. Their purpose is formative: use them to reveal which assumption produced your answer, then revisit the nearby explanation if the feedback identifies a gap. They do not duplicate the calculations and trade-off prompts in the chapter worksheets.

Using a Knowledge Check

Choose an answer before expanding any surrounding summary. After checking it, read the feedback for both correct and incorrect options. Incorrect choices usually represent a plausible confusion, such as treating a shared reward as individual credit or treating centralized training as communication at execution.

Checks by Course Stage

• Background: interpret the agent-environment loop, joint actions, local observations, shared rewards, and Dec-POMDP components.
• Coordinate: predict failures of independent learning, distinguish CTDE mechanisms, and interpret value factorizations.
• Communicate: reason about useful messages, channel constraints, learned conventions, and protocol failures.
• Adapt: diagnose partner dependence and evaluate evidence about unseen partners.
• Challenge Lab and final project: transfer concepts to unfamiliar system descriptions and evaluation choices.
