The models in this package specialize on modifying existing methods.
How to Cite
The following models are implemented.
FeasibilityFormNLS: Creates residual variables and constraints, so that the residual is linear.
FeasibilityResidual: Creates a nonlinear least squares model from an equality constrained problem in which the residual function is the constraints function.
LBFGSModel: Creates a model using a LBFGS approximation to the Hessian using an existing NLPModel.
LSR1Model: Creates a model using a LSR1 approximation to the Hessian using an existing NLPModel.
SlackModel: Creates an equality constrained problem with bounds on the variables using an existing NLPModel.
SlackNLSModel: Creates an equality constrained nonlinear least squares problem with bounds on the variables using an existing NLSModel.
See the documentation for details on the models.
