Reversible programming languages and computing represent a forward‐looking paradigm in which every computational operation is designed to be invertible. In these systems, each transition from one ...

In this article, we study some new characterizations of primitive recursive functions based on restricted forms of primitive recursion, improving the pioneering work of R. M. Robinson and M. D.

Having stumbled upon Project Euler sometime ago and solving the first problem, this disco dancer from the Age of Aquarius thought it was time to tackle problem two, which states: Each new term in the ...
