Weak Head Normal Form
Weak Head Normal Form - An expression in weak head normal form has been evaluated to the outermost data constructor or lambda abstraction (the head). Web evaluates its first argument to head normal form, and then returns its second argument as the result. So, seq forced the list to be evaluated but not the components that make. Web the first argument of seq is not guaranteed to be evaluated before the second argument. This means a redex may appear inside a lambda body. An expression is in weak head normal form (whnf), if it is either: Whnf [ (\x.y) z ] = false (1) whnf [ \x. Aside from a healthy mental workout, we find lambda calculus is sometimes superior: And once i read through them i thought i got it. Reduction strategies [ edit ]
And once i read through them i thought i got it. Normal form means, the expression will be fully evaluated. A constructor (eventually applied to arguments) like true, just (square 42) or (:) 1. Web the first argument of seq is not guaranteed to be evaluated before the second argument. Seq is defined as follows. Weak head normal form means, the expression will only evaluate as far as necessary to reach to a data constructor. Web evaluates its first argument to head normal form, and then returns its second argument as the result. The first argument of seq will only be evaluated to weak head normal form. Web weak head normal form. Therefore, every normal form expression is also in weak head normal form, though the opposite does not hold in general.
This means a redex may appear inside a lambda body. Normal form means, the expression will be fully evaluated. Web the first argument of seq is not guaranteed to be evaluated before the second argument. Alonzo church was alan turing’s doctoral advisor, and his lambda calculus predates turing machines. (f x) ] = false (2) whnf [ x y ] = whnf [ x ] (3) in all other cases whnf [x] = true (4) Section 6 de ne these normal forms. So, seq forced the list to be evaluated but not the components that make.
