Thus, it gives the worst-case complexity of an algorithm. There are mainly three asymptotic notations:īig-O notation represents the upper bound of the running time of an algorithm. These durations are denoted using asymptotic notations. When the input array is neither sorted nor in reverse order, then it takes average time. the best case.īut, when the input array is in reverse condition, the algorithm takes the maximum time (quadratic) to sort the elements i.e. The study of change in performance of the algorithm with the change in the order of the input size is defined as asymptotic analysis.Īsymptotic notations are the mathematical notations used to describe the running time of an algorithm when the input tends towards a particular value or a limiting value.įor example: In bubble sort, when the input array is already sorted, the time taken by the algorithm is linear i.e. With the increase in the input size, the performance will change. The efficiency is measured with the help of asymptotic notations.Īn algorithm may not have the same performance for different types of inputs. The efficiency of an algorithm depends on the amount of time, storage and other resources required to execute the algorithm. Decrease Key and Delete Node Operations on a Fibonacci Heap.
