WebJan 29, 2015 · And regardless, since the Fibonacci sequence grows exponentially, it will always require exponential time to compute just due to the size of the output. The matrix or "doubling" approach takes you from O(exp x2) to O(exp x) asymptotic calculation time, which isn't nothing, but it still isn't exactly tractable either. Share Cite Follow WebApr 22, 2024 · The fact that a float is produced when the exponent is negative is probably due to Python assuming that it effectively needs to do a division, which is reasonable. All things considered, rather than doing the exponentiation - which is common in pure math, because of simplicity of analysis - you should consider doing the "piece-wise" thing instead.

WebMay 5, 2024 · For Example, when we applied memoization to a recursive algorithm with O(2^n) complexity, we saw a massive performance boost. In this case, accessing a cache is much faster than repeating a calculation. Memoization allows us to use the recursive Fibonacci algorithm. However, the iterative calculation is still superior.
