Constrainted Nonlinear Optimization - lack of convergence
...used). All constraints are smooth, i.e. I can differentiate easily to produce heq.jac and hin.jac functions. My initial solution is feasible; I am attempting to maximize a function, phi. As such, I create an objective or cost function '-phi', and the gradient of the cost function '-dphi/dz'. I will gladly provide the detailed code, but perhaps an overview of the problem may be sufficient. 0. I installed 'alabama' and was successful at solving the example problem. 1. My constraints are: z=0 (for several elements in the vector z) z>=0 (for remaining elements in...
