The eight queens puzzle is a special case of the more general n queens problem of placing n non-attacking queens on an n × n chessboard. Solutions exist for all natural numbers n with the exception of n = 2 and n = 3. Although the exact number of solutions is only known for n ≤ 27, the asymptotic growth rate of the number of solutions is ...
(n)Code (n)Code Solutions, a subsidiary of GNFC, produces digital certificates for the Government of India (including the digital Aadhaar card for over 1 billion Indians). The solution was the result of a partnership with Entrust .
No-code development platform. No-code development platforms ( NCDPs) allow creating application software through graphical user interfaces and configuration instead of traditional computer programming based on writing code . No-code development platforms are closely related to low-code development platforms as both are designed to expedite the ...
Overdetermined system. In mathematics, a system of equations is considered overdetermined if there are more equations than unknowns. [1] [citation needed] An overdetermined system is almost always inconsistent (it has no solution) when constructed with random coefficients. However, an overdetermined system will have solutions in some cases, for ...
A linear code of length n and dimension k is a linear subspace C with dimension k of the vector space where is the finite field with q elements. Such a code is called a q -ary code. If q = 2 or q = 3, the code is described as a binary code, or a ternary code respectively. The vectors in C are called codewords.
CODE n. CODE_n is a business started in 2011 by GFT Technologies AG under the direction of CEO Ulrich Dietz. From 2012 to 2018, the company ran a contest at the CeBIT exhibition for startups with business models based on digital technologies. Additionally, CODE_n had workspaces and other events to help bring together startups and established ...
The P versus NP problem is a major unsolved problem in theoretical computer science. Informally, it asks whether every problem whose solution can be quickly verified can also be quickly solved. Here, quickly means an algorithm that solves the task and runs in polynomial time exists, meaning the task completion time varies as a polynomial ...
Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.
The first error-correcting code was the Hamming(7,4) code, developed by Richard W. Hamming in 1950. This code transforms a message consisting of 4 bits into a codeword of 7 bits by adding 3 parity bits. Hence this code is a block code. It turns out that it is also a linear code and that it has distance 3.
Legacy system. In 2011, MS-DOS was still used in some enterprises to run legacy applications, such as this US Navy food service management system. In computing, a legacy system is an old method, technology, computer system, or application program, "of, relating to, or being a previous or outdated computer system", [1] yet still in use.
