Detailed Description

This is the central class for the optimization. It is, however, not usable directly by the parser.

Member Function Documentation

float optimizer::get_consequence_probability	(	const belief &	b1,
		const action &	a,
		const visible_state &	vs
	)		const

Calculates the probability of the consequence (visible state).

const action * optimizer::get_optimal_action	(	const belief &	b,
		int	n
	)

Returns the optimal action given a belief and n (depth).

float optimizer::get_payoff_expected_value_for_consequences	(	const belief &	b1,
		int	n,
		const action &	a
	)

private

Returns the expected value of the payoff over the consequences.

void optimizer::on_error_in_populate_belief_for_consequence	(	const belief &	b1,
		const action &	a,
		const visible_state &	vs,
		belief &	target
	)		const

protectedvirtual

This function throws an error. It can be overriden to operate more smoothly, for example make the target a uniform belief.

void optimizer::populate_belief_for_consequence	(	const belief &	b1,
		const action &	a,
		const visible_state &	vs,
		belief &	target
	)		const

Calculates the belief (probability distribution over a visible state) given a visible state as consequence.
