iv
Continue at time zero. At time one stop on the lower branch and continue on the upper branch:
τ0​={1,2,​ξ1​=7,ξ1​=11.​​
(1)
This is a stopping time since the branch decision is measurable at time one. Its expected reward is
Eξτ0​​=53​7+52​(32​13+31​10)=9.​
(2)
It therefore attains the upper bound in part (iii).
