Students with disabilities or who need special assistance with exams or other aspects of the course are asked to let Prof. Tucker know about their circumstances at the
beginning of the course.
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. Any suspected instance of academic
dishonesty will be reported to the Academic Judiciary. For more comprehensive
information on academic integrity, including categories of academic dishonesty,
please refer to the academic judiciary website at http:
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. Faculty in the HSC Schools and
the school of Medicine are required to follow their school-specific
procedures. Further information about most academic matters can be
found in the Undergraduate Bulletin, the Undergraduate Class
Schedule, and the Faculty-Employee Handbook.
Mastermind Extra Credit:In the first month of the course, there will be weekly Mastermind puzzles posted
on this webpage each Thursday night at 10:00 pm.
Mastermind is explained in the Prelude at the front of the
textbook. The first five students to email the correct solution (with an
explanation of their reasoning) will get
3 extra points on the first test; the next five students to e-mail me the correct
sequence will get 2 extra points on the first test and the next 5 students will get one extra point on the first test.
Learning Outcomes for AMS 301
1.) Strengthen logical reasoning skills to solve combinatorial problems using:
* elements of propositional calculus;
* proof by contradiction;
* logical consequences of assumptions.
2.) Learn to find multiple (equally valid) ways to solve a combinatorics problem
* apply a top-down strategy (breaking a problem into parts and subparts)
* apply a bottom-up strategy (solving special subcases and building up).
* learn to solve problems from first principles, rather than looking for existing templates or formulas.
* solve a complementary problem;
* use different strategies to categorize subcases of a problem;
3.) Learn basic graph theory results and apply them in problem-solving:
* planar graphs;
* Hamilton circuits and Euler cycles;
* graph coloring;
* trees and ways to search them.
4.) Use formulas for counting basic combinatorial outcomes to construct solutions to more complex combinatorial enumeration problems:
* permutations, with and without repetition;
* combinations, with and without repetition.
5.) Apply counting strategies to solve discrete probability problems.
6.) Use specialized techniques to solve combinatorial enumeration problems:
* generating functions;
* recurrence relations;
* inclusion-exclusion principle.
NOTE THAT PROBLEMS ARE FROM THE SIXTH EDITION OF THE TEXTBOOK. THE NUMBERING
AND WORDING OF MANY PROBLEMS IS DIFFERENT IN EARLIER EDITIONS.
