The HybridLocalSearchModel type exposes the following members.

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. |

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. |

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.) |

Name | Description | |
---|---|---|

IGoalModel.AddGoal | Adds a goal to the collection. | |

IGoalModel.ClearGoals | Clears all the goals from a model. | |

IGoalModel.GetGoalFromIndex | Returns a goal entry if the row index is associated with a goal row. | |

IGoalModel.GoalCount | Gets a count of the number of goals for the search model. | |

IGoalModel.Goals | Gets the goals for the search model. | |

IGoalModel.IsGoal(Int32) | Returns a value that specifies whether a row index is a goal row. | |

IGoalModel.IsGoal(Int32, IGoal) | Returns a value that specifies whether a row index is a goal row, and returns the associated goal. | |

IGoalModel.RemoveGoal | Removes the specified goal. | |

IRowVariableModel.AddRow | Adds a row to a model. | |

IRowVariableModel.AddVariable | Adds a user variable to a model. | |

IRowVariableModel.GetBounds | Returns the bounds for a variable. | |

IRowVariableModel.GetIgnoreBounds | Returns a value that indicates whether the bounds of a variable are ignored. | |

IRowVariableModel.GetIndexFromKey | ||

IRowVariableModel.GetIntegrality | Gets the integrality of the goal identified by the specified index. | |

IRowVariableModel.GetKeyFromIndex | ||

IRowVariableModel.GetValue | Returns the value that is associated with a variable index. | |

IRowVariableModel.Indices | Gets the indices for the search model. | |

IRowVariableModel.IntegerIndexCount | Gets the index count as an integer for the search model. | |
