Optimization problemIn mathematics, computer science and economics, an optimization problem is the problem of finding the best solution from all feasible solutions. Optimization problems can be divided into two categories, depending on whether the variables are continuous or discrete: An optimization problem with discrete variables is known as a discrete optimization, in which an object such as an integer, permutation or graph must be found from a countable set.
Moroccan architectureMoroccan architecture reflects Morocco's diverse geography and long history, marked by successive waves of settlers through both migration and military conquest. This architectural heritage includes ancient Roman sites, historic Islamic architecture, local vernacular architecture, 20th-century French colonial architecture, and modern architecture. Much of Morocco's traditional architecture is marked by the style that developed during the Islamic period, from the 7th century onward.
Moorish architectureMoorish architecture is a style within Islamic architecture which developed in the western Islamic world, including al-Andalus (on the Iberian peninsula) and what is now Morocco, Algeria, and Tunisia (part of the Maghreb). Scholarly references on Islamic architecture often refer to this architectural tradition by a more geographic designation, such as architecture of the Islamic West or architecture of the Western Islamic lands. The use of the term "Moorish" comes from the historical Western European designation of the Muslim inhabitants of these regions as "Moors".
Public broadcastingPublic broadcasting, sometimes public service broadcasting, is not subject to political interference or commercial influence. Public broadcasters receive funding from diverse sources including license fees, individual contributions, public financing and commercial financing. Common mediums include AM and FM radio, shortwave radio, television and the Internet. Public broadcasting may be nationally or locally operated, depending on the country and the station. In some countries a single organization runs public broadcasting.
Worker cooperativeA worker cooperative is a cooperative owned and self-managed by its workers. This control may mean a firm where every worker-owner participates in decision-making in a democratic fashion, or it may refer to one in which management is elected by every worker-owner who each have one vote. Worker cooperatives rose to prominence during the Industrial Revolution as part of the labour movement. As employment moved to industrial areas and job sectors declined, workers began organizing and controlling businesses for themselves.
NumberA number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words. More universally, individual numbers can be represented by symbols, called numerals; for example, "5" is a numeral that represents the number five. As only a relatively small number of symbols can be memorized, basic numerals are commonly organized in a numeral system, which is an organized way to represent any number.
Public-access televisionPublic-access television (sometimes called community-access television) is traditionally a form of non-commercial mass media where the general public can create content television programming which is narrowcast through cable television specialty channels. Public-access television was created in the United States between 1969 and 1971 by the Federal Communications Commission (FCC), under Chairman Dean Burch, based on pioneering work and advocacy of George Stoney, Red Burns (Alternate Media Center), and Sidney Dean (City Club of NY).
Packet analyzerA packet analyzer, also known as packet sniffer, protocol analyzer, or network analyzer, is a computer program or computer hardware such as a packet capture appliance that can analyze and log traffic that passes over a computer network or part of a network. Packet capture is the process of intercepting and logging traffic. As data streams flow across the network, the analyzer captures each packet and, if needed, decodes the packet's raw data, showing the values of various fields in the packet, and analyzes its content according to the appropriate RFC or other specifications.
Hamiltonian path problemIn the mathematical field of graph theory the Hamiltonian path problem and the Hamiltonian cycle problem are problems of determining whether a Hamiltonian path (a path in an undirected or directed graph that visits each vertex exactly once) or a Hamiltonian cycle exists in a given graph (whether directed or undirected). Both problems are NP-complete.
Set theorySet theory is the branch of mathematical logic that studies sets, which can be informally described as collections of objects. Although objects of any kind can be collected into a set, set theory, as a branch of mathematics, is mostly concerned with those that are relevant to mathematics as a whole. The modern study of set theory was initiated by the German mathematicians Richard Dedekind and Georg Cantor in the 1870s. In particular, Georg Cantor is commonly considered the founder of set theory.
