Problem: Herbert Alexander Simon (June 15, 1916 - February 9, 2001) was an American economist and political scientist whose primary interest was decision-making within organizations and is best known for the theories of "bounded rationality" and "satisficing". He received the Nobel Prize in Economics in 1978 and the Turing Award in 1975. His research was noted for its interdisciplinary nature and spanned across the fields of cognitive science, computer science, public administration, management, and political science. He was at Carnegie Mellon University for most of his career, from 1949 to 2001.

Simon was a pioneer in the field of artificial intelligence, creating with Allen Newell the Logic Theory Machine (1956) and the General Problem Solver (GPS) (1957) programs. GPS may possibly be the first method developed for separating problem solving strategy from information about particular problems. Both programs were developed using the Information Processing Language (IPL) (1956) developed by Newell, Cliff Shaw, and Simon. Donald Knuth mentions the development of list processing in IPL, with the linked list originally called "NSS memory" for its inventors. In 1957, Simon predicted that computer chess would surpass human chess abilities within "ten years" when, in reality, that transition took about forty years.  In the early 1960s psychologist Ulric Neisser asserted that while machines are capable of replicating "cold cognition" behaviors such as reasoning, planning, perceiving, and deciding, they would never be able to replicate "hot cognition" behaviors such as pain, pleasure, desire, and other emotions. Simon responded to Neisser's views in 1963 by writing a paper on emotional cognition, which he updated in 1967 and published in Psychological Review. Simon's work on emotional cognition was largely ignored by the artificial intelligence research community for several years, but subsequent work on emotions by Sloman and Picard helped refocus attention on Simon's paper and eventually, made it highly influential on the topic.  Simon also collaborated with James G. March on several works in organization theory.  With Allen Newell, Simon developed a theory for the simulation of human problem solving behavior using production rules. The study of human problem solving required new kinds of human measurements and, with Anders Ericsson, Simon developed the experimental technique of verbal protocol analysis. Simon was interested in the role of knowledge in expertise. He said that to become an expert on a topic required about ten years of experience and he and colleagues estimated that expertise was the result of learning roughly 50,000 chunks of information. A chess expert was said to have learned about 50,000 chunks or chess position patterns.  He was awarded the ACM Turing Award, along with Allen Newell, in 1975. "In joint scientific efforts extending over twenty years, initially in collaboration with J. C. (Cliff) Shaw at the RAND Corporation, and subsequentially [sic] with numerous faculty and student colleagues at Carnegie Mellon University, they have made basic contributions to artificial intelligence, the psychology of human cognition, and list processing."

Question:
The term "Moors" refers primarily to the Muslim inhabitants of the Maghreb, the Iberian Peninsula, Sicily, and Malta during the Middle Ages. The Moors initially were the Berber autochthones of the Maghreb. The name was later also applied to Arabs. Moors are not a distinct or self-defined people, and the 1911 Encyclopaedia Britannica observed that "The term 'Moors' has no real ethnological value."
The first Muslim conquest of Sicily began in 827, though it was not until 902 that almost the entire island was in the control of the Aghlabids, with the exception of some minor strongholds in the rugged interior. During that period some parts of southern Italy fell under Muslim control, most notably the port city of Bari, which formed the Emirate of Bari from 847-871. In 909 the Aghlabid dynasty was replaced by Shiite Fatimids. Four years later, the Fatimid governor was ousted from Palermo when the island declared its independence under Emir Ahmed ibn-Kohrob. The language spoken in Sicily under Muslim rule was Siculo-Arabic.  In 1038, a Byzantine army under George Maniaces crossed the strait of Messina. This army included a corps of Normans that saved the situation in the first clash against the Muslims from Messina. After another decisive victory in the summer of 1040, Maniaces halted his march to lay siege to Syracuse. Despite his success, Maniaces was removed from his position, and the subsequent Muslim counter-offensive reconquered all the cities captured by the Byzantines.  The Norman Robert Guiscard, son of Tancred, invaded Sicily in 1060. The island was split between three Arab emirs, and the Christian population in many parts of the island rose up against the ruling Muslims. One year later, Messina fell, and in 1072 Palermo was taken by the Normans. The loss of the cities, each with a splendid harbor, dealt a severe blow to Muslim power on the island. Eventually all of Sicily was taken. In 1091, Noto in the southern tip of Sicily and the island of Malta, the last Arab strongholds, fell to the Christians. Islamic authors noted the tolerance of the Norman kings of Sicily. Ibn al-Athir wrote: "They [the Muslims] were treated kindly, and they were protected, even against the Franks. Because of that, they had great love for King Roger."  The Muslim problem characterized Hohenstaufen rule in Sicily under Holy Roman Emperors Henry VI and his son Frederick II. Many repressive measures were introduced by Frederick II to please the popes, who were intolerant of Islam in the heart of Christendom. This resulted in a rebellion by Sicilian Muslims, which in turn triggered organized resistance and systematic reprisals and marked the final chapter of Islam in Sicily. The complete eviction of Muslims and the annihilation of Islam in Sicily was completed by the late 1240s when the final deportations to Lucera took place.
