Fast evaluation of polynomials For evaluation of a general polynomial in one variable, the provably fastest method is Horner's scheme as Emil has pointed out. It is worth mentioning that this scheme has a more popular face in the form of little Bézout's theorem paired with Synthetic division as is often taught in Precalculus courses in the U.S.A.

- Breadth-first search (BFS) is an algorithm for traversing or searching tree or graph data structures.ote that initially the queue Q contains only the starting node v, but its adjacent nodes are immediately added to the queue Q in the for loop starting at line 16. Line 14: When we dequeue a node u from Q, it means that we are going to visit all the adjacent nodes of u.

Sorting algorithm Practical general sorting algorithms are almost always based on an algorithm with average time complexity (and generally worst-case complexity) O(n log n), of which the most common are heap sort, merge sort, and quicksort.

Top Ten Reasons Climate Change is a Hoax It's true in practice that solving NP-complete problems takes greater than polynomial time on a real computer, but that's not what it means, it's just the current state of the art, as a consequence of the fact that P=NP is unknown.

- TL;DR: The fastest algorithm looks at every element once, keeping track of the largest one seen so far. Details. Intuition tells us that any correct algorithm must look at every element in the array, that's why we can't do better. Let's find an actual proof.

- While converting it to a string then to an int works, it's a somewhat hackish method. We have all the information we need to make a number, namely:1  The digits. 2  The position of the digits.dit 2: With very large tuples: Length 20: Length 100: Here we see that the fastest method is actually the string operation-however, the reality is you are unlikely to be using this outside of the range of, say, 10 digit numbers-where the reduce() method still dominates speed-wise.

Algorithm Implementation/Strings/Longest common substring Common dynamic programming implementations for the Longest Common Substring algorithm runs in O(nm) time. All of these implementations also use O(nm) storage. The astute reader will notice that only the previous column of the grid storing the dynamic state is ever actually used in computing the next column.

- Reply. For now the best option is Python cause it’s having multiple web scraping libraries avail. As far as the speed is concerned, it’s not the language but rather a server (incl. its confuguration), which requests the web pages, that plays the main role in a fast content extraction.

The Importance of Algorithms While doing so does not improve the algorithm in the worst case, it often makes very good algorithms in the average case. Quicksort is a good example of an algorithm where randomization is often used. In the worst case, quicksort sorts a group of items in O(N2), where N is the number of items.

Which are the 10 algorithms every computer science student must implement at least once in life? 1 Some of those algorithms are a result of nature & biology studies. My favorite, a little different by nature, is the Ant Colony Optimization (ACO).  Kalman Filter - That is a classical algorithm that is used in radar systems, robotics, and quite a lot of applications where GPS (location data) is involved.

- A* Search: Combines uniform cost search (i.e. expand node on path with lowest cost so far) and greedy search. Evaluation function is f ( n ) = g ( n ) + h ( n ) {\displaystyle f(n)=g(n)+h(n)} (or estimated cost of the cheapest solution through node n).

Intel's crazy fast 72-core chip will appear in supercomputers next year Xeon Phi chips are used in the world's fastest supercomputer, code-named Tianhe-2, which is installed in China. Knights Landing will succeed the current version of Xeon Phi, code-named Knights Corner, which has 61 cores. Like its predecessors, Knights Landing will be a coprocessor alongside CPUs and assist in complex calculations.

Encyclopedia Tiny Encryption Algorithm is a very fast and moderately secure cipher produced by David Wheeler and Roger Needham of Cambridge Computer Laboratory. There is a known weakness in the key schedule, so it is not recommended if utmost security is required. TEA is provided in 16 and 32 round versions.

Loading.. Loading.. The Rubik's Revenge (aka the Master Cube) has 4x4x4 blocks, making it harder to solve than the original Rubik's Cube. This puzzle was released in 1981 and was actually invented not by professor Rubik himself but by Péter Sebestény. The most common algorithm for solving the Rubik's Revenge is called the reduction method.

- Mergesort is guarenteed to be O(n lg n), but has a higher memory footprint than quick sort. Quicksort generally runs faster than mergesort, but under ~some~ circumstances it can degrade to quadratic running time. Radix sort is O(n*r) where r is the length of the numbers. To determine if radix is better than your chosen lg-n method, do this: So if n is less than 2^32 (4 billion) then use the lg-n algorithm. Personally, I'd use quick sort, shuffling it if I have to in order to prevent it from degrading.
