The HybridLocalSearchModel type exposes the following members.

Constructors

	Name	Description
	HybridLocalSearchModel	A solver that uses simple, general-purpose local search strategies. Can be used for discrete and continuous, linear and non-linear, satisfaction and/or optimization models. This solver is incomplete: it does not guarantee optimality.

Properties

	Name	Description
	ConstraintsCount	Specifies the number of constraints.
	GoalsCount	Specifies the number of goals.
	RandomSeed	Sets the random seed that (re)initializes the random number sequence generation.
	Step	Specifies the current step number of the search when it is running.
	Violation	Identifies the violation of the current state.

Methods

	Name	Description
	AddConstant	Adds a constant to the model. Constants are considered rows.
	AddConstraint	Specifies that a numerical term is a constraint
	AddFunction
	AddGoal	Specifies that a numerical term is a goal to minimize. Priorities are determined by the order in which the goals are added (first goals have higher priorities)
	AddOperation(TermModelOperation, Int32%, Int32)	Adds an operation row to the model.
	AddOperation(TermModelOperation, Int32%, Int32())	Adds an operation row to the model.
	AddOperation(TermModelOperation, Int32%, Int32, Int32)	Adds an operation row to the model.
	AddOperation(TermModelOperation, Int32%, Int32, Int32, Int32)	Adds an operation row to the model.
	AddVariable(Int32%, IEnumerable<Rational>)	Adds a variable to the model, with a fixed set of possible values.
	AddVariable(Object, Int32%, IEnumerable<Rational>)	Adds a variable to the model, with a fixed set of possible values.
	AddVariable(Int32%, Rational, Rational, Boolean)	Adds a variable to the model, with bounds and integrality given at creation time.
	AddVariable(Object, Int32%, Rational, Rational, Boolean)	Adds a variable to the model, with bounds and integrality given at creation time.
	CreateBinaryFunction
	CreateNaryFunction
	CreateUnaryFunction
	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.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetOperand	Gets an operand associated with a vid.
	GetOperandCount	Gets the number of operands associated with a vid.
	GetOperands	Gets the operands associated with a vid.
	GetOperation	Gets the operation associated with a vid.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsConstant	Tests if a vid is a constant (not a variable or operation).
	IsOperation	Tests if a vid is an operation (not a variable or constant).
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RemoveConstraint	Removes a Boolean term from the set of constraints
	RequestTermination	Requests the end of the search algorithm
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Fields

	Name	Description
	goalList	Represents the goals, or objectives to minimize or maximize
