Last updated

SatZ is a well known SAT instance solver. It was developed by Prof. Chu Min Li, a computer science researcher. The Z stands for the last version of SAT solvers.

In logic and computer science, the Boolean satisfiability problem is the problem of determining if there exists an interpretation that satisfies a given Boolean formula. In other words, it asks whether the variables of a given Boolean formula can be consistently replaced by the values TRUE or FALSE in such a way that the formula evaluates to TRUE. If this is the case, the formula is called satisfiable. On the other hand, if no such assignment exists, the function expressed by the formula is FALSE for all possible variable assignments and the formula is unsatisfiable. For example, the formula "a AND NOT b" is satisfiable because one can find the values a = TRUE and b = FALSE, which make = TRUE. In contrast, "a AND NOT a" is unsatisfiable.

Five Dynasties and Ten Kingdoms period Period of Chinese history 907–979

The Five Dynasties and Ten Kingdoms period (907–979) was an era of political upheaval and division in 10th-century Imperial China. Five states quickly succeeded one another in the Central Plain, and more than a dozen concurrent states were established elsewhere, mainly in South China. It was the last prolonged period of multiple political divisions in Chinese imperial history.

Teochew is a dialect of Chaoshan Min, a Southern Min language, that is spoken by the Teochew people in the Chaoshan region of eastern Guangdong and by their diaspora around the world. It is sometimes referred to as Chiuchow, its Cantonese rendering, due to the English romanisation by colonial officials and explorers. It is closely related to some dialects of Hokkien, as it shares some cognates and phonology with Hokkien, although the two are not largely mutually intelligible.

Liu Yan, né Liu Yan (劉巖), also known as Liu Zhi (劉陟) and briefly as Liu Gong (劉龔), formally Tianhuang Dadi (天皇大帝) with the temple name Gaozu (高祖), was the first emperor of the Chinese Five Dynasties and Ten Kingdoms period state Southern Han.

The Mangic languages, which include the Pakanic languages, constitute a branch of Austroasiatic languages. They are spoken in southern China and northern Vietnam. The Mangic languages consist of Mang and two Pakanic languages, Bolyu and Bugan.

In computer science and mathematical logic, the satisfiability modulo theories (SMT) problem is a decision problem for logical formulas with respect to combinations of background theories expressed in classical first-order logic with equality. Examples of theories typically used in computer science are the theory of real numbers, the theory of integers, and the theories of various data structures such as lists, arrays, bit vectors and so on. SMT can be thought of as a form of the constraint satisfaction problem and thus a certain formalized approach to constraint programming.

Li Jing (Southern Tang) Emperor Yuanzong of (Southern) Tang

Li Jing, originally Xu Jingtong (徐景通), briefly Xu Jing (徐璟) in 937–939, courtesy name Boyu (伯玉), also known by his temple name Yuanzong (元宗), was the second ruler of imperial China's Southern Tang state during the Five Dynasties and Ten Kingdoms period. He reigned his state from 943 until his death.

<i>Chor Lau-heung</i> (1985 TV series)

Chor Lau-heung is a Taiwanese television series adapted from Chu Liuxiang Xinzhuan of Gu Long's Chu Liuxiang novel series. Adam Cheng starred as the titular protagonist, Chor Lau-heung. The series was divided into four parts, each lasting 4 to 6 episodes and with a different director. It was first broadcast on CTV in Taiwan in 1985. The series is an unofficial sequel to the 1979 Hong Kong TVB TV series of the same title, with the story continuing from where the 1979 series left off. The character Su Rongrong does not appear in this series because the character died at the end of the 1979 series.

Kiong Nai is a divergent Hmongic (Miao) language spoken in Jinxiu County, Guangxi, China. The speakers' autonym is pronounced or ; means 'mountain', while means 'people'. Mao & Li (2002) believe it to be most closely related to She.

Augmented Lagrangian methods are a certain class of algorithms for solving constrained optimization problems. They have similarities to penalty methods in that they replace a constrained optimization problem by a series of unconstrained problems and add a penalty term to the objective; the difference is that the augmented Lagrangian method adds yet another term, designed to mimic a Lagrange multiplier. The augmented Lagrangian is related to, but not identical with the method of Lagrange multipliers.

Hm Nai is a Hmong-Mien language spoken in western Hunan province, China. There are approximately 5800 people speaking this language, and the number is decreasing. Mao & Li (1997) determined it to be closely related to the Pa-Hng language.

Kuan, is a poorly classified Austroasiatic language spoken by about 1,000 people in Jinghong County, Xishuangbanna, Yunnan, China. Li (2005) proposes that it is a Mangic language. Other possible affiliations include Palaungic and Khmuic.

Bian Hao (邊鎬), nickname Kangle (康樂), was a general of the Chinese Five Dynasties and Ten Kingdoms Period state Southern Tang. Early in his career, he distinguished himself in campaigns against the agrarian army leader Zhang Yuxian and against Southern Tang's southeastern neighbor Min. Later, during Chu's collapse due to civil war, Bian was able to enter its territory and, for some time, secured the nominal submission of all of its territory for his emperor Li Jing. However, he was unable to deal with subsequent uprisings in the Chu realm and had to abandon it, causing him to be exiled for some time. He also fared poorly when later returned to the army, as he was defeated and captured by Later Zhou forces when Later Zhou invaded Southern Tang and eventually forced its submission as a vassal. After he was returned to Southern Tang, he had no further army commissions.

Miniature X-ray Solar Spectrometer CubeSat

The Miniature X-ray Solar Spectrometer (MinXSS) CubeSat was the first launched National Aeronautics and Space Administration Science Mission Directorate CubeSat with a science mission. It was designed, built, and operated primarily by students at the University of Colorado Boulder with professional mentorship and involvement from professors, scientists, and engineers in the Aerospace Engineering Sciences department and the Laboratory for Atmospheric and Space Physics, as well as Southwest Research Institute, NASA Goddard Space Flight Center, and the National Center for Atmospheric Research's High Altitude Observatory. The mission principal investigator is Dr. Thomas N. Woods and co-investigators are Dr. Amir Caspi, Dr. Phil Chamberlin, Dr. Andrew Jones, Rick Kohnert, Professor Xinlin Li, Professor Scott Palo, and Dr. Stanley Solomon. The student lead was Dr. James Paul Mason, who has since become a Co-I for the second flight model of MinXSS.
