SyntaxThe BoltzmannExploration type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | BoltzmannExploration |
Initializes a new instance of the BoltzmannExploration class.
|
Properties| Name | Description | |
|---|---|---|
 | Temperature |
Temperature parameter of Boltzmann distribution. Should be greater than 0.
|
Methods| Name | Description | |
|---|---|---|
| ChooseAction |
Choose an action.
|
| 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 the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Extension Methods| Name | Description | |
|---|---|---|
 | HasMethod |
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.) |
| IsEqual |
Compares two objects for equality, performing an elementwise
comparison if the elements are vectors or matrices.
(Defined by Matrix.) |
| To(Type) | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) |
| ToT | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.

RemarksThe class implements exploration policy base on Boltzmann distribution. Acording to the policy, action a at state s is selected with the next probability:
exp( Q( s, a ) / t )
p( s, a ) = -----------------------------
SUM( exp( Q( s, b ) / t ) )
bwhere Q(s, a) is action's a estimation (usefulness) at state s and t is Temperature.
