Unformatted text preview: 1 University of Southern California Daniel J. Epstein Department of Industrial and Systems Engineering ISE 582: Web Technology for Industrial Engineering Midterm: Chase/Tovey’s Chickens Instructor: Elaine Chew Distributed 10pm, Wednesday, 22 Oct 2003 Due 10pm, Thursday, 23 Oct 2003 OPEN BOOK NOTE: You are expected to complete the midterm on your own without external help. Please review the Academic Integrity Policy described on the course syllabus in case of doubt. The following question is based on Ivan Chase and Craig Tovey’s chicken dominance hierarchy research. Scientists have found that animals in groups tend to form dominance hierarchies that are transitive and acyclic, meaning that, if A dominates B, and B dominates C, then A dominates C. In an attempt to observe, quantify and analyze the formation of dominance hierarchies, Tovey, studies the behavior of chicken in pairwise confrontations. These observations are documented in text files such as chicken.txt. Each text file documents the final pecking order among four chickens and the details of each encounter as shown in “chicken.txt”. In the text file, J = jump P = peck I = inched away from For example, 2J3 means that chicken 2 jumped on chicken 3; 1P3 means that chicken 1 pecked chicken 3; and, 4I2 means that chicken 4 inched away from...
