我想在SICStus Prolog中看到谓词目标内的执行时间.
示例:
pred :-
goal1,
time,
goal2,
time.
go :-
call(pred).
time_go :-
go,
times(go).
预期结果:
?- time_go.
times_go = 1000ms ,
times_go_goal1 = 500ms,
times_go_goal2 = 500ms
怎么做 ？
我尝试过time_out(:Goal, +Time, -Result),library(timeout)但是我收到了这个错误:
| ?- time_out(char_code(a,N), T, Res).
! Instantiation error in argument 2 of user:time_out/3
! goal: time_out(user:char_code(a,_193),_179,_181)
| ?- time_out(char_code(a,N), 1000, Res).
N = 97,
Res = success ? ; % Res=timeout in other example
