Learning Algorithm summary

• Mentally play through possible future scenarios, giving priority to promising paths, whilst also considering how others are most likely to react to your actions and continuing to explore the unknown.

• After reaching a state that is unfamiliar, evaluate how favourable you believe the position to be and cascade the score back through previous positions in the mental pathway that led to this point.

• After you’ve finished thinking about future possibilities, take the action that you’ve explored the most.

• At the end of the game, go back and evaluate where you misjudged the value of the future positions and update your understanding accordingly.
