Processing a Decision Tree

Connecticut Electronics


The original decision tree

The Original Decision Tree


Go as far to the right as possible and pick a terminal node

Go as far to the right as possible, and pick a terminal node


Back up one step landing on either a chance node or a choice node

Back up one step, landing on either a chance node or a choice node


At a chance node put the following expectation

At a chance node, put thefollowing expectation


Go as far to the right as possible and pick a terminal node1

Go as far to the right as possible, and pick a terminal node


Back up one step landing on either a chance node or a choice node1

Back up one step, landing on either a chance node or a choice node


At a chance node put the following expectation1

At a chance node, put thefollowing expectation


Go as far to the right as possible and pick a terminal node2

Go as far to the right as possible, and pick a terminal node


Back up one step landing on either a chance node or a choice node2

Back up one step, landing on either a chance node or a choice node


At a choice node put the chosen following payoff and record the choice

At a choice node, put the chosen following payoff and record the choice

“sampled and good”: process


Go as far to the right as possible and pick a terminal node3

Go as far to the right as possible, and pick a terminal node

“sampled and good”: process


Back up one step landing on either a chance node or a choice node3

Back up one step, landing on either a chance node or a choice node

“sampled and good”: process


At a choice node put the chosen following payoff and record the choice1

At a choice node, put the chosen following payoff and record the choice

“sampled and good”: process

“sampled and bad”: replate


Go as far to the right as possible and pick a terminal node4

Go as far to the right as possible, and pick a terminal node

“sampled and good”: process

“sampled and bad”: replate


Back up one step landing on either a chance node or a choice node4

Back up one step, landing on either a chance node or a choice node

“sampled and good”: process

“sampled and bad”: replate


At a chance node put the following expectation2

At a chance node, put thefollowing expectation

“sampled and good”: process

“sampled and bad”: replate

When finished, you’re left with the optimal “choice” strategy, and the expected payoff yielded by following that strategy.
