WebJan 27, 2014 · In general, there is no algorithm for converting a recursive form into an iterative one. This problem is undecidable. As an example, consider this recursive function definition, which defines the Collatz sequence: f (1) = 0 f (2n) = 1 + f (n) f (2n + 1) = 1 + f (6n + 4) It's not known whether or not this is even a well-defined function or not. WebJun 3, 2011 · If the recurrence relation is linear, homogeneous and has constant coefficients, here is the way to solve it. First obtain the characteristic equation. To do this, assume f ( n) = m n. Plug it in to get a quadratic in m. Solve for m. Get the two roots say m 1 and m 2. Now the general solution is given by the linear combination namely f ( n) = a ...

WebNov 20, 2024 · We have seen that it is often easier to find recursive definitions than closed formulas. Lucky for us, there are a few techniques for converting recursive definitions to closed formulas. Doing so is called solving a recurrence relation.
