Graph theory
In mathematics and computer science, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of vertices (also called nodes or points) which are connected by edges (also called arcs, links, or lines). A distinction is made between undirected graphs, where edges link two vertices symmetrically, and directed graphs, where edges link two vertices asymmetrically. Graphs are one of the principal objects of study in discrete mathematics.

Graph homomorphism
In the mathematical field of graph theory, a graph homomorphism is a mapping between two graphs that respects their structure. More concretely, it is a function between the vertex sets of two graphs that maps adjacent vertices to adjacent vertices.

Homomorphisms generalize various notions of graph colorings and allow the expression of an important class of constraint satisfaction problems, such as certain scheduling or frequency assignment problems.
The fact that homomorphisms can be composed leads to rich algebraic structures: a preorder on graphs, a distributive lattice, and a category (one for undirected graphs and one for directed graphs).
The computational complexity of finding a homomorphism between given graphs is prohibitive in general, but a lot is known about special cases that are solvable in polynomial time. Boundaries between tractable and intractable cases have been an active area of research.

Job (professional wrestling)
In professional wrestling slang, a job is a losing performance in a wrestling match. It is derived from "doing one's job,” a euphemism to hide kayfabe-related information. When a wrestler is booked to lose a match, it is described as "a job". The act itself is  jobbing, whereas the act of booking (rather than being booked) to job is called jobbing out. To lose a match fairly (meaning without any kayfabe rules being broken) is to job cleanly.

Wrestlers who routinely (or exclusively) lose matches are known as jobbers or "dummy wrestlers". A wrestler skilled at enhancing the matches they lose, as opposed to a jobber, is called a carpenter. In the post-kayfabe era the term has taken on a negative connotation, leading to the use of the neutral term enhancement talent.

WWF Wrestling Challenge
WWF Wrestling Challenge is a professional wrestling television show that was produced by the World Wrestling Federation (WWF, now known as WWE). It was syndicated weekly and aired from 1986 to 1995. Near the end of the program's run, it was simply known as WWF Challenge.

The show featured matches, pre-match interviews, and occasionally, summarized weekly events in WWF programming. Matches primarily saw top-tier and mid-level talent vs. Jobbers. At times, there was a "feature" match between main WWF talent. As with other syndicated WWF programming, the show promoted WWF event dates and house shows in local media markets. It was the 'B' show of WWF syndication, meaning it generally only aired in markets where WWF had two weekly slots, with the other taken up by WWF Superstars of Wrestling.

Dungeon crawl
A dungeon crawl is a type of scenario in fantasy role-playing games (RPGs) in which heroes navigate a labyrinth environment (a "dungeon"), battling various monsters, avoiding traps, solving puzzles, and looting any treasure they may find. Video games and board games which predominantly feature dungeon crawl elements are considered to be a genre.

Fantasy
Fantasy is a genre of speculative fiction that involves supernatural or magical elements, often including completely imaginary realms and creatures.

The genre's roots lie in fantasy literature and drama. From the twentieth century onward, it has expanded into various media, including film, television, graphic novels, manga, animation, and video games.

The expression fantastic literature is often used for this genre by Anglophone literary critics. An archaic spelling for the term is phantasy.

Fantasy is generally distinguished from the genres of science fiction and horror by an absence of scientific or macabre themes, although these can occur in fantasy. In popular culture, the fantasy genre predominantly features settings that reflect the actual Earth, but with some sense of otherness.

Reinforced concrete
Reinforced concrete, also called ferroconcrete or ferro-concrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (known as rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion.

Robert Maillart
Robert Maillart (16 February 1872 – 5 April 1940) was a Swiss civil engineer who revolutionized the use of structural reinforced concrete with such designs as the three-hinged arch and the deck-stiffened arch for bridges, and the beamless floor slab and mushroom ceiling for industrial buildings. His Salginatobel (1929–1930) and Schwandbach (1933) bridges changed the aesthetics and engineering of bridge construction dramatically and influenced decades of architects and engineers after him. In 1991 the Salginatobel Bridge was declared an International Historic Civil Engineering Landmark by the American Society of Civil Engineers.
Mongols
Mongols are an East Asian ethnic group native to Mongolia and China (Inner Mongolia and other 11 autonomous territories), as well as the republics of Buryatia and Kalmykia in Russia. The Mongols are the principal member of the large family of Mongolic peoples. The Oirats and the Buryats are classified either as distinct ethno-linguistic groups or as subgroups of Mongols.

The Mongols are bound together by a common heritage and ethnic identity, descending from the Proto-Mongols. Their indigenous dialects are collectively known as the Mongolian language. The contiguous geographical area in which the Mongols primarily live is referred to as the Mongol heartland, especially in discussions of the Mongols' history under the Mongol Empire.

Timurid dynasty
The Timurid dynasty, self-designated as Gurkani, was the ruling dynasty of the Timurid Empire (1370–1507). It was a Sunni Muslim dynasty or Barlās clan of Turco-Mongol origin descended from the warlord Timur (also known as Tamerlane). The word "Gurkani" derives from Gurkân (گورکان)—a Persianized form of the Mongolian word kürgen, meaning 'son-in-law'. This was an honorific title used by the dynasty as the Timurids were in-laws of the line of Genghis Khan, founder of the Mongol Empire, as Timur had married Saray Mulk Khanum, a direct descendant of Genghis Khan. Members of the Timurid dynasty signaled the Timurid Renaissance, and they were strongly influenced by Persian culture and established two significant empires in history, the Timurid Empire (1370–1507) based in Persia and Central Asia, and the Mughal Empire (1526–1857) based in the Indian subcontinent.
Brazos River
The Brazos River (/ˈbræzəs/ ⓘ BRAZ-əs, Spanish: [ˈbɾasos]), called the Río de los Brazos de Dios (translated as "The River of the Arms of God") by early Spanish explorers, is the 14th-longest river in the United States at 1,280 miles (2,060 km) from its headwater source at the head of Blackwater Draw, Roosevelt County, New Mexico to its mouth at the Gulf of Mexico with a 45,000-square-mile (116,000 km2) drainage basin.

The river is closely associated with Texas history, particularly the Austin settlement and Texas Revolution eras. Today major Texas institutions such as Texas Tech University, Baylor University, and Texas A&M University are located close to the river's basin, as are parts of metropolitan Houston.

Old Three Hundred
The "Old Three Hundred" were 297 grantees who purchased 307 parcels of land from Stephen Fuller Austin in Mexican Texas. Each grantee was head of a household, or in some cases, a partnership of unmarried men. Austin was an American approved in 1822 by Mexico as an empresario for this effort, after the nation had gained independence from Spain. By 1825,  the colony had a population of 1,790, including 443 enslaved African Americans. Because the Americans believed they needed enslaved workers, Austin negotiated with the Mexican government to gain approval, as the new nation was opposed to slavery. Mexico abolished it in 1829.

The colony encompassed an area that ran from the Gulf of Mexico on the south, to near present-day Jones Creek in Brazoria County, Brenham in Washington County, Navasota in Grimes County, and La Grange in Fayette County. It was the first authorized colony of Anglo-American settlers and enslaved African Americans in Mexico.

Battle of Fuentes de Oñoro
The Battle of Fuentes de Oñoro was a military engagement that took place from 3–5 May 1811 during the Peninsular War. An Anglo-Portuguese Army under Wellington checked an attempt by the French Army of Portugal under Marshal André Masséna to relieve the besieged city of Almeida. The French defeat at Fuentes de Oñoro, in addition to the steadfastness of the allies and the formidable high ground and fortified position held by Wellesley, was further facilitated by the poor cooperation between Masséna and his subordinates. As Wellington stated, if Napoleon had been at Fuentes, "we should have been beat."

Lines of Torres Vedras
The Lines of Torres Vedras were lines of forts and other military defences built in secrecy to defend Lisbon during the Peninsular War. Named after the nearby town of Torres Vedras, they were ordered by Arthur Wellesley, Viscount Wellington, constructed by Colonel Richard Fletcher and his Portuguese workers between November 1809 and September 1810, and used to stop Marshal Masséna's 1810 offensive. The Lines were declared a National Heritage by the Portuguese Government in March 2019.
