Weak Head Normal Form
Weak Head Normal Form - Web 1 there are already plenty of questions about weak head normal form etc. But more importantly, working through the theory from its original viewpoint exposes us to different ways of thinking. Now, i have following expression: And once i read through them i thought i got it. Web the first argument of seq is not guaranteed to be evaluated before the second argument. The evaluation of the first argument of seq will only happen when the. Section 6 de ne these normal forms. An expression in weak head normal form has been evaluated to the outermost data constructor or lambda abstraction (the head). Therefore, every normal form expression is also in weak head normal form, though the opposite does not hold in general. Web there is also the notion of weak head normal form:
Reduction strategies [ edit ] An expression is in weak head normal form (whnf), if it is either: Seq is defined as follows. (f x) ] = false (2) whnf [ x y ] = whnf [ x ] (3) in all other cases whnf [x] = true (4) Weak head normal form means, the expression will only evaluate as far as necessary to reach to a data constructor. Therefore, every normal form expression is also in weak head normal form, though the opposite does not hold in general. Web i have question about weak head normal form and normal form. Web reduce terms to weak normal forms only. So, seq forced the list to be evaluated but not the components that make. Alonzo church was alan turing’s doctoral advisor, and his lambda calculus predates turing machines.
