env_mux_execute()

double env_mux_execute	(	const struct XCSF *	xcsf,
		const int	action
	)

Returns the reward for executing a multiplexer action.

Parameters

[in]	xcsf	The XCSF data structure.
[in]	action	The selected action.

Returns

The payoff from performing the action.

env_mux_free()

void env_mux_free

(

const struct XCSF *

xcsf

)

Frees the multiplexer environment.

Parameters

[in]

xcsf

The XCSF data structure.

env_mux_get_state()

const double* env_mux_get_state

(

const struct XCSF *

xcsf

)

Returns a random multiplexer problem instance.

Parameters

[in]

xcsf

The XCSF data structure.

Returns

A random multiplexer problem.

Here is the call graph for this function:

env_mux_init()

void env_mux_init	(	struct XCSF *	xcsf,
		const int	bits
	)

Initialises a real multiplexer environment of specified length.

The biggest mux problem is chosen that fits the specified length.

Parameters

[in]	xcsf	The XCSF data structure.
[in]	bits	The problem length.

env_mux_is_done()

bool env_mux_is_done

(

const struct XCSF *

xcsf

)

Returns whether the multiplexer is in a terminal state.

Parameters

[in]

xcsf

The XCSF data structure.

Returns

True.

Definition at line 121 of file env_mux.c.

env_mux_maxpayoff()

double env_mux_maxpayoff

(

const struct XCSF *

xcsf

)

Returns the maximum payoff value possible in the multiplexer.

Parameters

[in]

xcsf

The XCSF data structure.

Returns

The maximum payoff.

env_mux_multistep()

bool env_mux_multistep

(

const struct XCSF *

xcsf

)

Returns whether the multiplexer is a multistep problem.

Parameters

[in]

xcsf

Returns

False.

Definition at line 145 of file env_mux.c.

env_mux_reset()

void env_mux_reset

(
