Hello Gilles, That is a good question. I don't know. I read through the webpage Apache Commons Math has for the optimization APIs and everything there appeared to be an optimization (minimization or maximization) not for solving to hit a custom target "y" value. I will look at the specific documentation for the specific class you mention and see if there is some way to do what I am looking for. Thanks.
