The Held–Karp algorithm, also called the Bellman–Held–Karp algorithm, is a dynamic programming algorithm proposed in 1962 independently by Bellman [1] and by Held and Karp [2] to solve the traveling salesman problem (TSP), in which the input is a distance matrix between a set of cities, and the goal is to find a minimum-length tour that visits each city exactly once before returning to ...
Project Euler (named after Leonhard Euler) is a website dedicated to a series of computational problems intended to be solved with computer programs. [1] [2] The project attracts graduates and students interested in mathematics and computer programming.
The Earley parser executes in cubic time in the general case (), where n is the length of the parsed string, quadratic time for unambiguous grammars (), [4] and linear time for all deterministic context-free grammars.
The No free lunch theorem, discussed below, proves that, in general, the strong sample complexity is infinite, i.e. that there is no algorithm that can learn the globally-optimal target function using a finite number of training samples.
The standard version of CYK operates only on context-free grammars given in Chomsky normal form (CNF). However any context-free grammar may be algorithmically transformed into a CNF grammar expressing the same language (Sipser 1997). The importance of the CYK algorithm stems from its high efficiency in certain situations.
Some hobbyists have developed computer programs that will solve Sudoku puzzles using a backtracking algorithm, which is a type of brute force search. [3] Backtracking is a depth-first search (in contrast to a breadth-first search), because it will completely explore one branch to a possible solution before moving to another branch.
CodeChef is an online educational and Programming Education platform. It began as an educational initiative in 2009 by Directi, an Indian software company.In 2020, it was purchased by Unacademy.
YouTube would give free access to its users, the more users, the more profit it can potentially make because it can in principle increase advertisement rates and will gain further interest of advertisers. [339] YouTube would sell its audience that it gains by free access to its advertising customers. [339]: 181
