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.

Add a description, image, and links to the primitive-recursive-functions topic page so that developers can more easily learn about it.

Self-organized lipid structures (protocells) have been proposed as an intermediate between nonliving material and cellular life. Synthetic production of model protocells can demonstrate the potential ...

To understand recursion, you must first understand recursion. You may think of recursion as a programming structure where a function calls itself. We call such a function a recursive function. Many ...

Abstract: In environmental modeling, the impact of fixed scatterers on the background environment can be effectively accounted for by using numerical Green's functions (NGF), which significantly ...

The paper is mainly an expository account of elementary recursion theory. In part I, some care is given to the discussion of the relationship between the mathematical concepts of recursive functions ...

Some languages, like PowerShell, have “anonymous recursive functions”. That is, normally, a function needs to use a name to refer to itself to recur. But “anonymous recursion” means the language has ...

Abstract: We present a novel lightweight hardware security primitive for wireless body sensor networks (WBSNs). Security of WBSNs is crucial and the security solution must be lightweight due to ...
