The HybridLocalSearchModel type exposes the following members.

Constructors

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

Methods

  Name Description
Public method AddConstant Adds a constant to the model. Constants are considered rows.
Public method AddConstraint Specifies that a numerical term is a constraint
Public method AddFunction
Public method 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)
Public method AddOperation(TermModelOperation, Int32%, Int32) Adds an operation row to the model.
Public method AddOperation(TermModelOperation, Int32%, Int32()) Adds an operation row to the model.
Public method AddOperation(TermModelOperation, Int32%, Int32, Int32) Adds an operation row to the model.
Public method AddOperation(TermModelOperation, Int32%, Int32, Int32, Int32) Adds an operation row to the model.
Public method AddVariable(Int32%, IEnumerable<Rational>) Adds a variable to the model, with a fixed set of possible values.
Public method AddVariable(Object, Int32%, IEnumerable<Rational>) Adds a variable to the model, with a fixed set of possible values.
Public method AddVariable(Int32%, Rational, Rational, Boolean) Adds a variable to the model, with bounds and integrality given at creation time.
Public method AddVariable(Object, Int32%, Rational, Rational, Boolean) Adds a variable to the model, with bounds and integrality given at creation time.
Public method CreateBinaryFunction
Public method CreateNaryFunction
Public method CreateUnaryFunction
Public method Equals Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetOperand Gets an operand associated with a vid.
Public method GetOperandCount Gets the number of operands associated with a vid.
Public method GetOperands Gets the operands associated with a vid.
Public method GetOperation Gets the operation associated with a vid.
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method IsConstant Tests if a vid is a constant (not a variable or operation).
Public method IsOperation Tests if a vid is an operation (not a variable or constant).
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method RemoveConstraint Removes a Boolean term from the set of constraints
Public method RequestTermination Requests the end of the search algorithm
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
