The UnconstrainedNonlinearModel type exposes the following members.

Constructors

	Name	Description
	UnconstrainedNonlinearModel	Creates a new instance of the UnconstrainedNonlinearModel class, by using the specified key comparer.

Properties

	Name	Description
	FunctionEvaluator	Function value callback.
	GradientEvaluator	Gradient callback.
	Indices	Returns the variable index collection, inclusive of rows
	KeyComparer	Is used for row or variable key comparison
	KeyCount	Returns the number of keys, inclusive of rows and variables.
	Keys	Returns the variable and row key collection. Indices are guaranteed to be greater than or equal to 0 and less than the KeyCount.
	RowCount	Returns the number of rows in the model
	RowIndices	Returns the row index collection
	RowKeys	Returns the row key collection
	RowValue	Sets the value of the only row of the model
	TheGoal	The only goal of the model
	VariableCount	Gets the number of variables in the model.
	VariableIndices	Gets an IEnumerable containing the variable indexes.
	VariableKeyCount	Returns a count for keys (not including null) for variables
	VariableKeys	Gets an IEnumerable containing the variable keys.

Methods

	Name	Description
	AddGoal	Marks a row as a goal.
	AddRow	Adds a row to the model.
	AddRowAsGoal	Adds a row as a goal. Unconstrained models can have just one row. By convention this row will always have 0 as an index.
	AddVariable	The method ensures that a user variable with the given key is in the model.
	CopyVariableValuesFrom	Copies variable values from an array.
	CopyVariableValuesTo	Copies variable values to an array.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetBounds	Returns the bounds for a vid.
	GetGoalFromIndex	Returns a goal entry if the row id is a goal
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetIndexFromKey	Maps the variable index from the key. If not found, KeyNotFoundException will be thrown
	GetKeyFromIndex	Maps the variable index to the key. If not found, ArgumentException will be thrown
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Gets the value associated with the variable index. This is typically used when retrieving results.
	IsGoal(Int32)	Checks if a row identified by the specified id is a goal row.
	IsGoal(Int32, IGoal%)	Checks if a row identified by the specified id is a goal row. If true, return the goal entry
	IsRow	Validates whether the specified id represents a row index
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	PreChange	Invoke this function before modfying the model.
	RemoveGoal	Removes a goal row
	SetBounds	Sets the upper and lower bounds for a vid.
	SetGoalValue	Sets the goal value.
	SetLowerBound	Sets the lower bound for a vid.
	SetUpperBound	Sets the upper bound for a vid.
	SetValue	Sets the value of model identified by the vid. The default value for a vid is Indeterminate.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TryGetIndexFromKey	Attempts to get the variable index based on the specified key
	ValidateVid	Validates a vid, and throws ArgumentException if not valid.

Explicit Interface Implementations

	Name	Description
	IGoalModel.ClearGoals	Clears all the goals
	IGoalModel.GoalCount	The number of goals in this model
	IGoalModel.Goals	Returns the goal collection of this model.
	INonlinearModel.GetActiveVariables	Specifies variables that participate in the row.
	INonlinearModel.IsActiveVariable	Determines whether a variable is active in a specific row
	INonlinearModel.SetActiveVariable	Sets a specific variable in a row to be active or inactive
	INonlinearModel.SetActiveVariables	Sets all variables in a row to be active or inactive
	IRowVariableModel.GetIgnoreBounds	Gets the flag that specifies whether bounds are ignored
	IRowVariableModel.GetIntegrality	Checks if a variable is an integer variable
	IRowVariableModel.IntegerIndexCount	Returns the number of integer variables
	IRowVariableModel.SetIgnoreBounds	Adjusts whether the bounds of a vid should be respected or ignored during solving. By default, bounds are respected.
	IRowVariableModel.SetIntegrality	Marks a variable as an integer variable
