public class BruteForceLineSearch : LineSearchMethod
The BruteForceLineSearch type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | BruteForceLineSearch | Initializes a new instance of the BruteForceLineSearch class. |
Properties| Name | Description | |
|---|---|---|
 | DivisionDepth | Gets or sets the maximum recursion depth for refining the minimum. |
| MethodName | Gets the method name. (Inherited from OptimizationMethod) |
| NumberOfInitialDivisions | Gets or sets the number of grid divisions used in the initial coarse search. |
| NumberOfSubsequentDivisions | Gets or sets the number of divisions used for each refinement step after the initial search. |
Methods| Name | Description | |
|---|---|---|
| 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) |
| FunctionEvaluation |
Performs an evaluation of the cost function value.
(Inherited from OptimizationMethod) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| GradientEvaluation |
Performs an evaluation of the cost function gradient.
(Inherited from OptimizationMethod) |
| HessianEvaluation |
Performs an evaluation of the cost function Hessian.
(Inherited from OptimizationMethod) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| Search(VectorDouble, VectorDouble, Double) | Minimizes the given cost function along a search direction. (Overrides LineSearchMethodSearch(VectorDouble, VectorDouble, Double)) |
| Search(VectorDouble, VectorDouble, Int32, Int32, Int32) | Searches for the minimum of the cost function on the line segment between two bounds. |
| ToString | Returns a string that represents the current object. (Inherited from OptimizationMethod) |
| ToString(IFormatProvider) | A string representation of this OptimizationMethod. (Inherited from OptimizationMethod) |
