Gets or sets 'auto' will turn on automatic variable handling, i.e. when you add constraints and objectives the variables in them will be added automatically (default), 'manual' will turn this feature off and you need to add variables manually to the model

public string Behavior { get; set; }

Public Property Behavior As String
	Get
	Set

public:
property String^ Behavior {
	String^ get ();
	void set (String^ value);
}
