## NewtonRaphsonMultivariableFunctionSolver Properties |

The NewtonRaphsonMultivariableFunctionSolver type exposes the following members.

Properties

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

Constraints |
Gets the constraint settings corresponding to the
results computed by the Function. There must be at least one
constraint set for this solver to work.
(Inherited from MultivariableFunctionSolver.) | |

CurrentIteration |
Gets or sets the number of the current iteration. This should be incremented in
the FindSolution(Int32, Boolean, ITrackCalculationProgress) method.
(Inherited from MultivariableFunctionSolver.) | |

Function |
Gets or sets the function to solve. When
the solver converges, this function must
have been run with the variable values that converged. This behavior must be obeyed when
Multithreaded is either or .
(Inherited from MultivariableFunctionSolver.) | |

IsThreadSafe |
Gets a value indicating whether the methods on this instance are safe to call from
multiple threads simultaneously.
(Overrides MultivariableFunctionSolverIsThreadSafe.) | |

LastRunsResults |
Gets or sets the results
of the solver run. This includes such information as if the solver converged,
all the iteration results (if configured to save them), if the run was aborted, etc.
(Inherited from MultivariableFunctionSolver.) | |

LineSearchSettings | Gets or sets an optional property that can be used to specify tolerances, convergence criteria, and maximum iterations for a line search that is used to find the optimal feasible step in the same direction as the computed step. The cost function that is minimized for the line search is the square root of the sum of the squares of the weighted and scaled constraint errors. GoldenSectionFindExtremum is used to find the minimum of the cost function along the direction of the computed step. | |

Multithreaded |
Gets or sets a value indicating whether this solver should evaluate an iteration with as many threads as the current threading
policy facet will allow, or with as many Variables
as there are in the function plus 1; whichever is less. By default this is .
(Overrides MultivariableFunctionSolverMultithreaded.) | |

Variables |
Gets the SolverVariableSettings that will be used when computing this function.
The variables passed to the function will be in the same order as this list of settings. There
must be at least one variable set for this solver to work.
(Inherited from MultivariableFunctionSolver.) |
