For problem 4, I used the same assumption stated in the problem. In computing optimal value of m, I came up with pretty complicated differential equations where exp(m) and erf(\sqrt{m}) is involved. I think it is almost impossible to be solved by hand. Do you want me to solve this equation, or is there any other way to obatin optimal value of m?
