Induction recursion
Web搞 induction recursion 的原因是要 formulate universe,universe 大家都知道简单來讲是 type of types。 引入 universe 的理由在 ITT 的原文是 To strengthen the language, we … WebRecursive definitions are technically unrestricted, whereas inductive definitions must usually have a well founded "induction principle" which actually lets you do induction (in the proof sense) on the object. Recursive definitions don't a priori give you inductive definitions, but an inductive definition is recursive.

In computer programming, there is a technique called recursion that is closely related to induction. In a computer program, a subroutine is a named sequence of instructions for performing a certain task. Web26 mei 2016 · Recursion Proof by Induction Ask Question Asked 6 years, 10 months ago Modified 4 years, 8 months ago Viewed 2k times 3 Given: f (1) = 2 f (n) = f (n-1) + 3, for all n>1 It can be evaluated to: f (1)=2 f (2)=f (2-1) + 3 = f (1) + 3 = 5 f (3)=f (3-1) + 3 = f (2) + 3 = 8 ... Or simply, f (n) = 3y-1 for all n>1 may be used to calculate f (n) directly.
Induction-recursion can be used to define large types including various universe constructions. It increases the proof-theoretic strength of type theory substantially. Nevertheless, inductive-recursive recursive definitions are still considered predicative. Meer weergeven In intuitionistic type theory (ITT), a discipline within mathematical logic, induction-recursion is a feature for simultaneously declaring a type and function on that type. It allows the creation of larger types, such as … Meer weergeven A simple common example is the Universe à la Tarski type former.
