Implementations of Gradient-Based Optimization Methods

• The optimizer LMMIN is a local minimizer of vector-valued quantities and is based on the LEVENBERG-MARQUARDT algorithm [242] from the MINPACK project [245,246].
• The software tool DONOPT is a local optimizer. It minimizes scalar-valued quantities and supports equality and inequality constraints [44,247,248]. This optimizer is based on the donlp2 algorithm [249,250].
