Method Detail

probability

double probability(S sDelta,
                   S s,
                   A a)

Return the probability of going from state s using action a to s' based on the underlying transition model P(s' | s, a).

Parameters:

sDelta - the state s' being transitioned to.

s - the state s being transitions from.

a - the action used to move from state s to s'.

Returns:

the probability of going from state s using action a to s'.
