Classes
class	MINOTAUR_AMPL::AMPLInterface
	Interface to read ampl models using AMPL Solver Library. AMPLInterface class provides methods to read and evaluate an instance from AMPL generated .nl files. It also provides methods to evaluate functions, gradients, jacobians and hessians. More...

Enumeration Type Documentation

ReaderType

enum MINOTAUR_AMPL::ReaderType

What kind of ASL reader is used to read the .nl file.

Enumerator
FGReader	No derivatives, linear objective and constraints only.
FGHReader	first derivatives. This reader will be used to read the expression tree.
PFGReader	First derivatives and Hessian-vector products. Need a loop for computing full hessian.
PFGHReader	First derivatives and partially separable structure. First and second derivatives and partially separable structure. Can compute full hessian. This reader is used when NLPs are solved by calling ASL's evaluation routines.
