C# 클래스 AForge.MachineLearning.RouletteWheelExploration

Roulette wheel exploration policy.

The class implements roulette whell exploration policy. Acording to the policy, action a at state s is selected with the next probability:

Q( s, a ) p( s, a ) = ------------------ SUM( Q( s, b ) ) b

where Q(s, a) is action's a estimation (usefulness) at state s.

The exploration policy may be applied only in cases, when action estimates (usefulness) are represented with positive value greater then 0.
