Weak Head Normal Form
Weak Head Normal Form - The first argument of seq will only be evaluated to weak head normal form. Normal form means, the expression will be fully evaluated. The evaluation of the first argument of seq will only happen when the. Weak head normal form means, the expression will only evaluate as far as necessary to reach to a data constructor. An expression is in weak head normal form (whnf), if it is either: Web the first argument of seq is not guaranteed to be evaluated before the second argument. Web lambda calculus is historically significant. Now, i have following expression: Web reduce terms to weak normal forms only. Web i have question about weak head normal form and normal form.
A term in weak head normal form is either a term in head normal form or a lambda abstraction. (f x) ] = false (2) whnf [ x y ] = whnf [ x ] (3) in all other cases whnf [x] = true (4) Alonzo church was alan turing’s doctoral advisor, and his lambda calculus predates turing machines. This means a redex may appear inside a lambda body. Section 6 de ne these normal forms. The evaluation of the first argument of seq will only happen when the. Whnf [ (\x.y) z ] = false (1) whnf [ \x. An expression is in weak head normal form (whnf), if it is either: Web lambda calculus is historically significant. Now, i have following expression:
An expression in weak head normal form has been evaluated to the outermost data constructor or lambda abstraction (the head). This means a redex may appear inside a lambda body. A term in weak head normal form is either a term in head normal form or a lambda abstraction. 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. Therefore, every normal form expression is also in weak head normal form, though the opposite does not hold in general.
