{"title":"An Integer Programming Quiz Picture Round","authors":"M. Chlond","doi":"10.1287/ITED.1120/0097","DOIUrl":"https://doi.org/10.1287/ITED.1120/0097","url":null,"abstract":"Pub quizzes have been a popular weekday evening activity in the United Kingdom for many years. These quizzes consist of a number of teams competing for a cash prize over several rounds of questions. Typical rounds may include general knowledge, music, science, sports, and current affairs. More recently, because of surreptitious use of smart phones it has become a challenge to quiz setters to devise questions that will confound the would-be cheat. As a result, rounds of picture questions have become increasingly prevalent and in this article I would like to present a particularly novel type of picture round based on the traveling salesman problem (TSP) or, more specifically, the TSP art pioneered by Bob Bosch and others. The TSP may be formulated using integer programming (IP) and is known to be NP-complete. The P versus NP problem is considered to be of such importance that the Clay Mathematics Institute included it as one of the millennium problems, offering a $1 million prize for its resolution. For an official description of the problem together with a video see http://www.claymath.org/millennium/P_vs_NP/. The TSP has generated a great deal of attention over the past few decades and researchers in this field have taken from and hugely contributed to the more general IP literature. William J. Cook’s terrific book In Pursuit of the Traveling Salesman (2012) gives a very detailed but accessible coverage of the problem and is essential reading for anyone with more than a passing interest in optimization. Cook (2012) includes a useful introduction to TSP art in a consciousness expanding chapter entitled Aesthetics. The basic idea is to generate TSP solutions that will approximate target images, usually portraits, when viewed at an appropriate distance. These are sometimes referred to as single line drawings and may be at the very least eye-catching and in some instances quite beautiful. In 2010 a sculpture called Embrace based on this idea gained Bosch the mathematical art exhibition first prize awarded by the American Mathematical Society and the Mathematics Association of America. This exquisite piece of mathematical artwork may be viewed at http://www .ams.org/mathimagery/displayimage.php?pid=274. Bosch, together with Craig Kaplan, has developed many sophisticated methods to enhance the aesthetic appeal of TSP images, see for example Kaplan and Bosch (2005) and their respective Web pages at http://www.oberlin.edu/math/faculty/bosch/tspartpage.html and http://www.cgl.uwaterloo.ca/~csk/ projects/tsp/. In this article I use the basic ideas to render images of iconic figures. My objective was to produce a range of images of varying clarity to be used as a basis for a quiz picture round. The process begins with a target image in the form of a black and white digital photograph as with the portrait of Marilyn Monroe in Figure 1. This target image is divided into rectangular panels and the average grayscale value of each panel is computed. The panels o","PeriodicalId":37137,"journal":{"name":"INFORMS Transactions on Education","volume":"13 1","pages":"65-66"},"PeriodicalIF":0.0,"publicationDate":"2012-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66511583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Martonosi","doi":"10.1287/ITED.1110.0066","DOIUrl":"https://doi.org/10.1287/ITED.1110.0066","url":null,"abstract":"In this case about two fictitious airlines, RegionEx, a small regional airline, is a contracted regional carrier for MississippiDelta Airlines (MDA), a major U.S. airline. In September, RegionEx exhibited a worse flight delay record than MDA, and is now at risk of losing its contract. The flight operations manager at RegionEx is tasked with analyzing the flight delay records and explaining RegionEx's seemingly poor performance to RegionEx's chief operations officer. Reflecting the recommendations of the Guidelines for Assessment and Instruction in Statistics Education (GAISE) published by the American Statistical Association, this case emphasizes statistical literacy and conceptual understanding of data analysis rather than rote procedures. Undergraduate and MBA students will use basic data analysis techniques, such as graphical analysis, descriptive statistics, and two-sample hypothesis testing and correlation, to discover important paradoxes in the flight delay data. They will learn that subtle differences in the definition of business performance metrics can radically change their interpretation; graphical analysis of data can provide information about distributions that are masked by summary statistics; aggregating data across disparate sample sizes can skew means (Simpson's paradox); and correlation does not imply causation.
