Function Documentation

left_mult_standard()

automaton_t awali::dyn::left_mult_standard	(	automaton_t	aut1,
		weight_t	w,
		options_t	opts = {}
	)

Produces an automaton that associates with every word the weight (w * x), where x is the weight associated with this word in aut.

The automaton must be standard. This function multiplies the weight of each outgoing transition of the initial state by w;

The following options may be given in opts: KEEP_HISTORY, IN_PLACE. (Other options are ignored)

If IN_PLACE is true, this operation operation is done directly on aut. In this case, KEEP_HISTORY is ignored.

If IN_PLACE is `false, this operation is done on a copy of aut.

Parameters

aut	a standard automaton
w	weight by which the initial weights are multiplied
opts	a set of options

Returns

a copy of aut in which the transition weights have been multiplied by w

right_mult()

automaton_t awali::dyn::right_mult	(	automaton_t	aut,
		weight_t	w,
		options_t	opts = {}
	)

Produces an automaton that associates with every word the weight (x * w), where x is the weight associated with this word in aut.

Consists in multiplying every final weight by w on the right.

The following options may be given in opts: KEEP_HISTORY, IN_PLACE. (Other options are ignored)

If IN_PLACE is true, this operation operation is done directly on aut. In this case, KEEP_HISTORY is ignored.

If IN_PLACE is false, this operation is done on a copy of aut.

Parameters

aut	automaton (unchanged)
w	weight by which the final are multiplied
opts	a set of options

Returns

a copy of aut in which the transition weights have been multiplied by w
