Bogosort

In computer science, bogosort (also permutation sort, stupid sort,slowsort,shotgun sort or monkey sort) is a particularly ineffective sorting algorithm based on the generate and test paradigm. The algorithm successively generates permutations of its input until it finds one that is sorted. It is not useful for sorting, but may be used for educational purposes, to contrast it with other more realistic algorithms.

Two versions of the algorithm exist: a deterministic version that enumerates all permutations until it hits a sorted one, and a randomized version that randomly permutes its input. An analogy for the working of the latter version is to sort a deck of cards by throwing the deck into the air, picking the cards up at random, and repeating the process until the deck is sorted. Its name comes from the word bogus.

Description of the algorithm

The following is a description of the randomized algorithm in pseudocode:

Running time and termination

If all elements to be sorted are distinct, the expected number of comparisons performed in the average case by randomized bogosort is asymptotically equivalent to , and the expected number of swaps in the average case equals . The expected number of swaps grows faster than the expected number of comparisons, because if the elements are not in order, this will usually be discovered after only a few comparisons, no matter how many elements there are; but the work of shuffling the collection is proportional to its size. In the worst case, the number of comparisons and swaps are both unbounded, for the same reason that a tossed coin might turn up heads any number of times in a row.

New Hampshire Wildcats

The New Hampshire Wildcats, or 'Cats, are the athletic teams of the University of New Hampshire. The wildcat is the school's official mascot, the colors are UNH Blue and white. There are 18 varsity sports, 25 sport clubs, and 23 different Intramural sports.

The men's and women's varsity teams compete at the NCAA Division I level; in football, it competes in the second tier of Division I, the Football Championship Subdivision (formerly Division I-AA). The football program plays in the Colonial Athletic Association, and the men's and women's hockey teams are members of Hockey East. The other teams compete in the America East, except for the ski teams and gymnastics team who compete in the East Atlantic Gymnastics League (EAGL) and Eastern Intercollegiate Ski Association (EISA) respectively.

Sports

UNH is a member of the America East Conference for basketball, cross country, soccer, and track and field; and women's field hockey, gymnastics, lacrosse, swimming & diving, and volleyball. They also compete in Hockey East in men's and women's ice hockey, in the East Atlantic Gymnastics League (EAGL) in women's gymnastics, in the Eastern Intercollegiate Ski Association (EISA) in men's and women's skiing, and at the Division I FCS level (formerly Division I-AA) in the Colonial Athletic Association for football.

Structure (mathematical logic)

In universal algebra and in model theory, a structure consists of a set along with a collection of finitary operations, and relations that are defined on it.

Universal algebra studies structures that generalize the algebraic structures such as groups, rings, fields and vector spaces. The term universal algebra is used for structures with no relation symbols.

Model theory has a different scope that encompasses more arbitrary theories, including foundational structures such as models of set theory. From the model-theoretic point of view, structures are the objects used to define the semantics of first-order logic. For a given theory in model theory, a structure is called a model, if it satisfies the defining axioms of that theory, although it is sometimes disambiguated as a semantic model when one discusses the notion in the more general setting of mathematical models. Logicians sometimes refer to structures as interpretations.

In database theory, structures with no functions are studied as models for relational databases, in the form of relational models.

Strategic Offensive Reductions Treaty

The Treaty Between the United States of America and the Russian Federation on Strategic Offensive Reductions (SORT), also known as the Treaty of Moscow, was a strategic arms reduction treaty between the United States and Russia that was in force from June 2003 until February 2011 when it was superseded by the New START treaty. At the time, SORT was positioned as "represent[ing] an important element of the new strategic relationship" between the two countries with both parties agreeing to limit their nuclear arsenal to between 1,700 and 2,200 operationally deployed warheads each. It was signed in Moscow on 24 May 2002. After ratification by the U.S. Senate and the State Duma, SORT came into force on 1 June 2003. It would have expired on 31 December 2012 if not superseded by New START. Either party could have withdrawn from the treaty upon giving three months written notice to the other.

Mutual nuclear disarmament

SORT was one in a long line of treaties and negotiations on mutual nuclear disarmament between Russia (and its predecessor, the Soviet Union) and the United States, which includes SALT I (1969–1972), the ABM Treaty (1972), SALT II (1972–1979), the INF Treaty (1987), START I (1991), START II (1993) and New START (2010).
