Is it possible to know what is the best way one can implement their own equation (constraint) as following...
F(x1, x2, x3, x4.......) = 0
F is very complex and I want user to supply functional values (residuals) and derivatives (with respect to each variables).
I would like to know what methods do I need to intercept (e.g eval_grad_f, eval_g, eval_jac_g, eval_h). Is it possible to get an example?
