Finding out the time complexity of your code can help you develop better programs that run faster. Some functions are easy to analyze, but when you have loops, and recursion might get a little trickier when you have recursion. After reading this post, you are able to derive the time comple...
Modifications of the most widespread algorithms reducing the amount of computations are proposed. Based on the complexities evaluated in the worst case and on the average for the modified algorithms, the fastest algorithm is found for each operation. A program that experimentally confirms theoretical ...
In the process of algorithm brushing, we will encounter various time complexities, but even if your code changes, you can hardly escape the following common time complexities.The time complexity in the above table increases from top to bottom, so O(1) is the most efficient, O(n) and O($...
In this paper, we present two offline algorithms for generating a lookup table of parameter settings that can be used by a complexity control algorithm for controlling the speed of the H.264 encoder. Our algorithms to design the lookup table of parameter settings take fewer than 2% of the ...

To see the difference between efficiently solvable and provably hard problems, consider the difference between an algorithm that requires a polynomial (e.g. n2) and one that requires an exponential (e.g. 2n) number of operations. If n=100, the former amounts to 10.000 steps whereas the ...
2). Notice also that our linear formulation does not suffer from the well-known convergence problems of the iterative FC algorithm29 and provides more regular solutions. Some comments on the obtained results are due to the reader. First, the original ECIc, PCIc, Fc and Qp variables are ...
