Question: What is the name of an American popular science magazine that included a discussion by Solomon W. Golomb and Martin Gardner on mutilated chessboard problem?

full_context: Document 1: Rep-tile: In the geometry of tessellations, a rep-tile or reptile is a shape that can be dissected into smaller copies of the same shape. The term was coined as a pun on animal reptiles by the American mathematician Solomon W. Golomb, who used it to describe self-replicating tilings. In 2012 a generalization of rep-tiles called self-tiling tile sets was introduced by Lee Sallows in "Mathematics Magazine".
Document 2: Molyneux's problem: Molyneux's problem is a thought experiment in philosophy concerning immediate recovery from blindness. It was first formulated by William Molyneux, and notably referenced in John Locke's "An Essay Concerning Human Understanding" (1689). The problem can be stated in brief, "if a man born blind can feel the differences between shapes such as spheres and cubes, could he, if given the ability to see (but now without recourse to touch), distinguish those objects by sight (alone), in reference to the tactile schemata he already possessed?"
Document 3: Inscribed square problem: The inscribed square problem, also known as the square peg problem or the Toeplitz' conjecture, is an unsolved question in geometry: "Does every plane simple closed curve contain all four vertices of some square?" This is true if the curve is convex or piecewise smooth and in other special cases. The problem was proposed by Otto Toeplitz in 1911. Some early positive results were obtained by Arnold Emch and Lev Schnirelmann. s of 2016 the general case remains open.
Document 4: Mutilated chessboard problem: The mutilated chessboard problem is a tiling puzzle proposed by philosopher Max Black in his book "Critical Thinking" (1946). It was later discussed by Solomon W. Golomb (1954), and by Martin Gardner in his "Scientific American" column "Mathematical Games". The problem is as follows:
Document 5: Quanta Magazine: Quanta Magazine is an editorially independent online publication of the Simons Foundation covering developments in mathematics, theoretical physics, theoretical computer science and the basic life sciences. The articles in the magazine are freely available to read online. Several publications like "Scientific American", "Wired", and "The Atlantic", as well as international science publications like "Spektrum der Wissenschaft", have reprinted articles from "Quanta Magazine". "Undark Magazine" described "Quanta Magazine" as "highly regarded for its masterful coverage of complex topics in science and math." The science news aggregator "RealClearScience" ranked "Quanta Magazine" No. 2 on its list of "The Top 10 Websites for Science in 2016." Initially launched as "Simons Science News" in October 2012, it was renamed to its current title in July 2013. The founding editor-in-chief is Thomas Lin. "Quanta's" editorial team includes John Rennie (editor), Michael Moyer, Natalie Wolchover, Kevin Hartnett, Olena Shmahalo, Lucy Reading-Ikkanda and Jeanette Kazmierczak. On 2 May 2017 "Quanta" introduced a complete redesign and rebranding of its website.
Document 6: Science News: Science News is an American bi-weekly magazine devoted to short articles about new scientific and technical developments, typically gleaned from recent scientific and technical journals. "Science News" has been published since 1922 by Society for Science & the Public, a non-profit organization founded by E. W. Scripps in 1920. American chemist Edwin Slosson served as the publication's first editor. From 1922 to 1966, it was called Science News Letter. The title was changed to "Science News" with the March 12, 1966 issue (vol. 89, no. 11).
Document 7: Harper's Magazine: Harper's Magazine (also called Harper's) is a monthly magazine of literature, politics, culture, finance, and the arts. Launched in June 1850, it is the second-oldest continuously published monthly magazine in the U.S. ("Scientific American" is the oldest,but did not become monthly until 1921). The current editor is James Marcus, who replaced Christopher Cox in March 2016. "Harper's Magazine" has won twenty National Magazine Awards.
Document 8: Subtract a square: Subtract-a-square (also referred to as take-a-square) is a two-player mathematical game of strategy. It is played by two people with a pile of coins (or other tokens) between them. The players take turns removing coins from the pile, always removing a non-zero square number of coins. The game is usually played as a "normal play" game, which means that the player who removes the last coin wins. It is an impartial game, meaning that the set of moves available from any position does not depend on whose turn it is. Solomon W. Golomb credits the invention of this game to Richard A. Epstein.
Document 9: Yale Scientific Magazine: The Yale Scientific Magazine (YSM) is a scientific magazine published quarterly by undergraduate students from Yale University. It was founded at the Sheffield Scientific School of Yale in 1894. Before 1927, it was originally called "Yale Scientific Monthly" or "Yale Sheffield Monthly". As the first student magazine devoted to the sciences, it is the oldest collegiate science quarterly in the United States.
Document 10: Scientific American Mind: Scientific American Mind is a bimonthly American popular science magazine concentrating on psychology, neuroscience, and related fields. By analyzing and revealing new thinking in the cognitive sciences, the magazine tries to focus on the biggest breakthroughs in these fields. "Scientific American Mind" is published by Nature Publishing Group which also publishes "Scientific American" and was established in 2004. The magazine has its headquarters in New York City.
Document 11: The Sciences: The Sciences was a magazine published from 1961 to 2001 by the New York Academy of Sciences. Each issue contained articles that discussed science issues with cultural relevance, illustrated with fine art and an occasional cartoon. The periodical won seven National Magazine Awards over the course of its publication.
Document 12: Hex (board game): Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus. Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain. One player must win; there are no draws. The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem. It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash. The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production. Hex can also be played with paper and pencil on hexagonally ruled graph paper.
Document 13: Scientific American: Scientific American (informally abbreviated SciAm) is an American popular science magazine. Many famous scientists, including Albert Einstein, have contributed articles in the past 170 years. It is the oldest continuously published monthly magazine in the United States(though it only became monthly in 1921).
Document 14: Puzzle: A puzzle is a game, problem, or toy that tests a person's ingenuity or knowledge. In a puzzle, the solver is expected to put pieces together in a logical way, in order to arrive at the correct solution of the puzzle. There are different genres of puzzles, such as crossword puzzles, word-search puzzles, number puzzles, or logic puzzles.
Document 15: Chomp: Chomp is a two-player strategy game played on a rectangular chocolate bar made up of smaller square blocks (cells). The players take it in turns to choose one block and "eat it" (remove from the board), together with those that are below it and to its right. The top left block is "poisoned" and the player who eats this loses.
