Problem: Light-emitting diode:

In the late 1980s, key breakthroughs in GaN epitaxial growth and p-type doping ushered in the modern era of GaN-based optoelectronic devices. Building upon this foundation, Dr. Moustakas at Boston University patented a method for producing high-brightness blue LEDs using a new two-step process. Two years later, in 1993, high-brightness blue LEDs were demonstrated again by Shuji Nakamura of Nichia Corporation using a gallium nitride growth process similar to Dr. Moustakas's. Both Dr. Moustakas and Mr. Nakamura were issued separate patents, which confused the issue of who was the original inventor (partly because although Dr. Moustakas invented his first, Dr. Nakamura filed first).[citation needed] This new development revolutionized LED lighting, making high-power blue light sources practical, leading to the development of technologies like BlueRay, as well as allowing the bright high resolution screens of modern tablets and phones.[citation needed]

Problem: Atlantic City, New Jersey:

During this time, Atlantic City was under the mayoral reign of Edward L. Bader, known for his contributions to the construction, athletics and aviation of Atlantic City. Despite the opposition of many others, he purchased land that became the city's municipal airport and high school football stadium, both of which were later named Bader Field in his honor. He led the initiative, in 1923, to construct the Atlantic City High School at Albany and Atlantic Avenues. Bader, in November 1923, initiated a public referendum, during the general election, at which time residents approved the construction of a Convention Center. The city passed an ordinance approving a bond issue for $1.5 million to be used for the purchase of land for Convention Hall, now known as the Boardwalk Hall, finalized September 30, 1924. Bader was also a driving force behind the creation of the Miss America competition.

What three contributions to Atlantic City was Edward L. Bader known for?
---
A: construction, athletics and aviation

---
A: Malenkov

Problem: IBM:

In 1952, Thomas Watson, Sr., stepped down after almost 40 years at the company helm; his son, Thomas Watson, Jr., was named president. In 1956, the company demonstrated the first practical example of artificial intelligence when Arthur L. Samuel of IBM's Poughkeepsie, New York, laboratory programmed an IBM 704 not merely to play checkers but "learn" from its own experience. In 1957, the FORTRAN (FORmula TRANslation) scientific programming language was developed. In 1961, Thomas J. Watson, Jr., was elected chairman of the board and Albert L. Williams became company president. The same year IBM developed the SABRE (Semi-Automatic Business-Related Environment) reservation system for American Airlines and introduced the highly successful Selectric typewriter.

What did Albert L. Willaims program to learn from its experience when playing checkers?
