We have learned how to calculate the Fibonacci sequence with recursive technique, but there are disadvantages while calculating the sequence with the orginal definition of Fibonacci: fib(k) = fib(k - 1) + fib(k - 2). Firstly, it takes long time to get the result with large k.

Fast Fibonacci algorithm (fast doubling method)

WebDeriving the fast doubling Fibonacci algorithm without using matrices ( O(logN) ) While playing around with the Fibonacci series. I found a way to compute nth Fibonacci number in Log(N) complexity. In the excitement, I searched on the net if the algorithm has been derived before. I found out that the algorithm is called as Fast Doubling algorithm.
