fzn_last(+FznState)

Increments solutions count, and succeeds if last one reached
FznState
a FlatZinc state descriptor

Description

Assuming a model has previously been loaded successfully using fzn_load_xxx or mzn_load_xxx, this primitive can be used to limit the number of solutions produced. It increments a nonlogical counter and fails as long as the number of solutions that were requested in the zn_options has not yet been reached.

Modes and Determinism

Fail Conditions

Fails if not enough solutions found yet

Examples

    my_fzn_run_stream(ModelStream, Options) :-
	fzn_init(Options, State),
	fzn_load_stream(ModelStream, State),
	fzn_search(State),
	fzn_output(State),
	fzn_last(State),
	!.
