Feb 16, 2015 · The closest an algorithm can get to this would be something like a backdoor in an encryption algorithm, where the planned flaw is part of the information relationship established …

Q&A for students, researchers and practitioners of computer science. Stack Exchange Network. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the …

Dec 23, 2020 · For large n, we usually define the time it takes to multiply two n-bit numbers as M(n). That time depends on how clever our algorithm is; what we learned in school has M(n) = …

For instance, all polynomial algorithms have runtime in $\cal{O}(2^n)$; therefore, such a bound might not characterise the algorithm well at all. In most cases, only worst-case instances are …

An algorithm is, alas, an informal concept, which can not have a precise mathematical definition. One can still attempt at an informal definition, and argue that it conveys the right (informal) …

$\begingroup$ You are asking two things: 1) An algorithm to decide whether a collection of tiles has a valid arrangement and 2) An algorithm to find a maximum size subcollection such that …

The best algorithm that is known is to express the factorial as a product of prime powers. One can quickly determine the primes as well as the right power for each prime using a sieve approach. …

The fastest algorithm I can think of is applying LCS in a creative way. It can solve this problem in O(N^2) time and O(N^2) space where N is the size of string. LCS (S, reverse (S)) will give you …

Mar 29, 2019 · Use background detection algorithm, say Gaussian Mixture-based background detection (present in OpenCv) and then make some assumption - say backround takes more …

Today there is no existing computer that can execute Shor's algorithm. To run Shor's algorithm, you need a quantum computer, which doesn't exist yet. Therefore, you shouldn't expect …
