WebSep 2, 2010 · A simplified answer is that primitive recursive functions are those which are defined in terms of other primitive recursive functions, and recursion on the structure of natural numbers. Natural numbers are conceptually like this: data Nat = Zero Succ Nat -- Succ is short for 'successor of', i.e. n+1 This means you can recurse on them like this: WebWe can start by thinking about primitive types, for example things like int s, float s, and str s. We also have ways to combine those things together into more complex structures like list s, set s, or dict s. We've seen an example of this idea already in lab 0, where we worked with structures like the following: WebApr 11, 2024 · This allows us to derive the provably total functions in $\mathbb T$ are exactly the primitive recursive ones, and establish some other constructive properties about $\mathbb T$. flexi school scotland
