Counting problem (computability theory) — In computability theory, a counting problem is a type of computational problem. If R is a search problem then :c R(x)=vert{ymid R(x,y)}vert ,is the corresponding counting function and:#R={(x,y)mid yleq c R(x)}denotes the corresponding counting… … Wikipedia
Counting problem (complexity) — In computational complexity theory and computability theory, a counting problem is a type of computational problem. If R is a search problem then is the corresponding counting function and denotes the corresponding counting problem. Note that cR… … Wikipedia
Counting — is the action of finding the number of elements of a finite set of objects. The traditional way of counting consists of continually increasing a (mental or spoken) counter by a unit for every element of the set, in some order, while marking (or… … Wikipedia
