They will determine with you what accommodations, if any, are necessary and appropriate. All information and documentation is confidential.

Academic Integrity: Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Faculty is required to report any suspected instances of academic dishonesty to the Academic Judiciary. Faculty in the Health Sciences Center (School of Health Technology & Management, Nursing, Social Welfare, Dental Medicine) and School of Medicine are required to follow their school-specific procedures. For more comprehensive information on academic integrity, including categories of academic dishonesty please refer to the academic judiciary website at http://www.stonybrook.edu/uaa/academicjudiciary/

Critical Incident Management: Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of University Community Standards any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn.

Learning outcomes for AMS 3031.) Develop skill with proofs in graph theory (this is the only Applied Math course that teaches proofs), including: * the careful use of definitions and stated conditions, and their consequences; * direct arguments; * indirect arguments, i.e., proof by contradiction; * proof with generalized figures. 2.) Examine graph theory topics in greater depth (than AMS 301) with a focus on studying and extending theoretical results: * general graph properties; * planar graphs; * graph coloring, including edge and face coloring. 3.) Understand the theory behind Polyabs Enumeration Formula and use this understanding in applied problem-solving. 4.) Develop the network algorithms for: * maximal minimal flows; * maximal matching; * the transportation problem. 5.) Understand the set-theoretic constructions underlying the theory of progressively finite games and apply this knowledge to develop winning strategies for such games: * kernel of a game; * level-by-level construction; * Grundy functions; * direct sums of games, including Nim. 6.) Use combinatorial reasoning to efficiently solve cryptograms based on keyword transpose encodings; extend this reasoning to solve polyalphabetic codes.COURSE OUTLINE:
