If values are not found for the previous two indexes, you will do the same to find values at that index. Then, you calculate the value of the required index as a sum of the values at the previous two indexes ( that is add values at the n-1 index and n-2 index). Source: Scaler Topics Algorithm for the Top-Down Approachįirst, you take the input ‘n’ to get the corresponding number in the Fibonacci Series. And we can break these modules down further into smaller fragments until they can not be fragmented anymore. We break the complex algorithm into smaller fragments that can be called modules. We use the tree kind of approach here – we just look for the previous two values and if those values are not available to us we repeat the process till the time we don’t get the two values. This is an approach that is Theory Driven. If their values are also not available to us, we repeat the same process until we don’t get the two values. If the previous two values are not available to us, we repeat the same process for them also. In this Top-Down approach, we compute the value of the required index as the sum of values at the previous two indexes. How to Compute the Fibonacci Series using the Top-Down Approach November 23 is Fibonacci Day, as the date on this day resembles the Fibonacci series in mm / dd format as it is (11/23).The ratio of any two consecutive numbers in the Fibonacci series is approximately 1.6.a part of the same ubiquitous music of the spheres that build harmony into atoms, molecules, crystals, shells, suns, and galaxies and makes the Universe sing.” ― Guy Murchie, The Seven Mysteries of Life: An Exploration of Science and Philosophy Do you Know These Facts? The importance of the Fibonacci series in nature is beautifully explained in Guy Murchie’s Quote “The Fibonacci Sequence turns out to be the key to understanding how nature designs. You can also see it in many natural processes. The Fibonacci series is used in many fields like finance and tech. It was first described in Indian mathematics. The Fibonacci series goes like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, … and so on. The Fibonacci Series is a special kind of sequence that starts with 0 and 1, and every number after those two is the sum of the two preceding numbers.
