I am trying to minimize an objective function with equality constraint of three parameters with lower and upper bounds. The function and equality constraint are programed and the gradient cannot be calculated. I tried NLOPT_LN_AUGLAG and it gave an error message NLOPT_LN_AUGLAG needs a local optimizer; specify an algorithm and termination condition in local_opts. Please tell how to put algorithm and termination condition in local_opts.
