The algorithm may very well take less time on some inputs of size n , but it doesn't matter. A popular alternative to worst-case analysis is average-case analysis. Here we do not bound the worst case running time, but try to calculate the expected time spent on a randomly chosen input. This kind of analysis is generally harder, since it involves probabilistic arguments and often requires assumptions about the distribution of inputs that may be difficult to justify. On the other hand, it can be more useful because sometimes the worst-case behavior of an algorithm is misleadingly bad.
A good example of this is the popular quicksort algorithm, whose worst-case running time on an input sequence of length n is proportional to n 2 but whose expected running time is proportional to n log n.
This does not always hold; the constants can sometimes make a difference, but in general it is a very good rule of thumb. We may not even be able to measure the constant c directly. For example, we may know that a given expression of the language, such as if , takes a constant number of machine instructions, but we may not know exactly how many. Moreover, the same sequence of instructions executed on a Pentium IV will take less time than on a Pentium II although the difference will be roughly a constant factor.
So these estimates are usually only accurate up to a constant factor anyway. For these reasons, we usually ignore constant factors in comparing asymptotic running times. Computer scientists have developed a convenient notation for hiding the constant factor.
We write O n read: ''order n '' instead of '' cn for some constant c. An algorithm is said to be O n 2 or quadratic time if there is a fixed constant c such that for all sufficiently large n , the algorithm takes time at most cn 2 on inputs of size n.

O 1 means constant time. Polynomial time means n O 1 , or n c for some constant c. Thus any constant, linear, quadratic, or cubic O n 3 time algorithm is a polynomial-time algorithm. This is called big-O notation. It concisely captures the important differences in the asymptotic growth rates of functions.argo-karaganda.kz/scripts/xabotojil/2996.php

As Markov sources are closely related to automata and transducers, our results can also be used for the asymptotic analysis of sequences which can be computed by transducers. Variance and covariance of several simultaneous outputs of a Markov chain. To carry out the desired asymptotic analysis , we need the following assumptions: Singularly perturbed multi-scale switching diffusions.
Drawing many of his examples from the classical functions of mathematical physics and probability theory, he uses them to introduce beginners in asymptotic analysis to the asymptotic phenomena of large-parameter problems and how to select certain representations, transformations, or other preparations to obtain a standard from.

One way would be to count the number of primitive operations at different input sizes. Though this is a valid solution, the amount of work this takes for even simple algorithms does not justify its use. Another way is to physically measure the amount of time an algorithm takes to complete given different input sizes.
Lecture Introduction to Asymptotic Analysis
However, the accuracy and relativity times obtained would only be relative to the machine they were computed on of this method is bound to environmental variables such as computer hardware specifications, processing power, etc. In the first section of this doc we described how an Asymptotic Notation identifies the behavior of an algorithm as the input size changes. Let us imagine an algorithm as a function f, n as the input size, and f n being the running time.

So for a given algorithm f, with input size n you get some resultant run time f n. This results in a graph where the Y axis is the runtime, X axis is the input size, and plot points are the resultants of the amount of time for a given input size. You can label a function, or algorithm, with an Asymptotic Notation in many different ways. Some examples are, you can describe an algorithm by its best case, worse case, or equivalent case.
The most common is to analyze an algorithm by its worst case. A very good example of this is sorting algorithms; specifically, adding elements to a tree structure. Best case for most algorithms could be as low as a single operation.
