I tried again and it works. Really appreciated!

By the way, I tried 0 as alpha value and it returns different kinds of
EXTERIOR, SINGULAR, REGULAR and INTERIOR in different situations. 
I don't konw why I just tried 0 because in an example it uses 0 as alpha
valus to build Alpha_shape_3:

list<Weighted_point> lwp;
Alpha_shape_3  as(lwp.begin(), lwp.end(), 0, Alpha_shape_3::GENERAL);
