WebCountability The last piece of the puzzle before we prove our claim that not all functions are computable is the concept of countability. Intuitively, our proof will show that there are more languages; that is, more problems than there are possible programs to solve them.

With these computational models in hand, we can determine what their limits are. That is, what classes of languages can they accept? Computer scientists call any language that can be accepted by a finite-state machine a regular language. Because of the restriction that the number of possible states in a finite state machine is finite, we can see that to find a language that is not regular, we must construct a language that … WebOne goal of computability theory is to determine which problems, or classes of problems, can be solved in each model of computation.

"WebTheorem: For all regular languages, L, with inﬁnitely many words, there exists a constant n (which depends on L) such that for all strings w 2 L, where jwj ‚ n, there exists a factoring of w = xyz, such that: † y 6= Λ. † jxyj • n. † For all k ‚ 0, xykz 2 L. Proof: 1. Since L is regular, there is an FA A that accepts L. 2. Let jQAj = n. 3. Since jLj = 1, there exists a word w ... " - Countability toc
