Try using the format from the examples in the help for Maximize.

If you change the commands slightly, to match the examples in the help on Maximize, the routine gives a good answer. I have attached a demonstration of how I got this to work.

Thank you but it does not work for other s

Dear Jed,
Thank you for the answer.

The problem is that it does not work for other s. For example, for s=0.1 it gives

Warning, no iterations performed as initial point satisfies first-order conditions

even though the correct answer is b=0.

I guess the difficulty comes from the fact that the optimal value of b jumps from 0 to 1 at s=0.18. For this reason I had the option "" so that Maximize looks for the global solution.
