Dear Ravi, As I've already written to you, the problem indeed is to find a solution to the transcendental equation y = x * T^(x-1), given y and T and the optimization problem below only a workaround. John C. Nash has been so kind to help me on here. In case anyone faces a similar problem in

Hi Uli, I am not sure if this is the problem that you really want to solve. The answer is the solution to the equation y = x * T^(x-1), provided a solution exists. There is no optimization involved here. What is the real problem that you are trying to solve? If you want to solve a more meaning
