Constraint with only linear terms.

Inheritance: IConstraint

Public Methods

Method	Description
GetViolation ( double input ) : double	Gets how much the constraint is being violated.
IsViolated ( double input ) : bool	Gets whether this constraint is being violated (within the current tolerance threshold).
LinearConstraint ( IObjectiveFunction function, Expression constraint ) : System	Constructs a new linear constraint.
LinearConstraint ( IObjectiveFunction function, string constraint ) : System	Constructs a new linear constraint.
LinearConstraint ( IObjectiveFunction function, string constraint, CultureInfo format ) : System	Constructs a new linear constraint.
LinearConstraint ( int numberOfVariables ) : System	Constructs a new linear constraint.
TryParse ( string str, CultureInfo culture, IObjectiveFunction function, LinearConstraint &constraint ) : bool	Attempts to create a LinearConstraint from a System.String representation.
TryParse ( string str, IObjectiveFunction function, LinearConstraint &constraint ) : bool	Attempts to create a LinearConstraint from a System.String representation.
