Advanced Encryption Standard process. The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process lasting from 1997 to 2000 that was markedly more open and transparent than its predecessor, the Data Encryption ...
The subset sum problem (SSP) is a decision problem in computer science. In its most general formulation, there is a multiset of integers and a target-sum , and the question is to decide whether any subset of the integers sum to precisely .[ 1] The problem is known to be NP-complete. Moreover, some restricted variants of it are NP-complete too ...
The two solutions with the vertical axis denoting time, s the start, f the finish and T the torch. The bridge and torch problem (also known as The Midnight Train [1] and Dangerous crossing [2]) is a logic puzzle that deals with four people, a bridge and a torch. It is in the category of river crossing puzzles, where a number of objects must ...
Google Code Jam was an international programming competition hosted and administered by Google. [ 2] The competition began in 2003. [ 3] The competition consists of a set of algorithmic problems which must be solved in a fixed amount of time. Competitors may use any programming language and development environment to obtain their solutions.
t. e. Game theory is the study of mathematical models of strategic interactions. [ 1] It has applications in many fields of social science, and is used extensively in economics, logic, systems science and computer science. [ 2] Initially, game theory addressed two-person zero-sum games, in which a participant's gains or losses are exactly ...
Contests. Wikipedia has various contests from time to time -- for good writing, site and logo designs, or great images or media -- to encourage and recognize brilliant, unusual, or specially-targeted contributions. Contests have also been run on various other Wikimedia projects, generally eliciting excitement and support; the Wikinews writing ...
The International Collegiate Programming Contest, known as the ICPC, is an annual multi-tiered competitive programming competition among the universities of the world. [ 1] Directed by ICPC Executive Director and Baylor Professor William B. Poucher, the ICPC operates autonomous regional contests covering six continents culminating in a global ...
A context model (or context modeling) defines how context data are structured and maintained (It plays a key role in supporting efficient context management). [1] It aims to produce a formal or semi-formal description of the context information that is present in a context-aware system. In other words, the context is the surrounding element for ...
