WebMar 24, 2024 · The Ackermann function is the simplest example of a well-defined total function which is computable but not primitive recursive, providing a counterexample to the belief in the early 1900s that every computable function was also primitive recursive (Dötzel 1991). It grows faster than an exponential function, or even a multiple exponential … WebHere is an example. Example2.4.3 Solve the recurrence relation an = an−1+n a n = a n − 1 + n with initial term a0 = 4. a 0 = 4.
