CS 473: Coursework

All solutions were removed after the semester ended.

Enemy HOMEWORK used MATH!  Student is CONFUSED!

Homeworks and solutions

All homeworks are due Tuesday at noon in the drop-boxes outside 1404 Siebel Center. We will post each week's homework at least one week before the due date; we will solutions at most a day after the due date. Don't forget to read the homework policies!

Be extra careful when you're answering the questions.

Online quizzes

All quizzes are available on the course Moodle site. Each week's quiz will be available at least a week before its due date.

Baby, you ain't kiddin'.

Head-banging Problems

We will post each week's head-banging problems here on Thursday, after everyone has had a chance to solve them from scratch. We will not post solutions; that would miss the point. However, we strongly encourage everyone to discuss the head-banging problems, and even post solutions for feedback, on Piazza. If any student posts a correct solution, we will certify it, and the student will get some extra credit.

And thery were all asking themselves the same question:
What is behind that curtain?

Exams and solutions

The problem is that we attempt to solve the simplest questions cleverly, thereby rendering them unusually complex. One should seek the simple solution.
— Anton Pavlovich Chekhov (c. 1890)
Thus you see, most noble Sir, how this type of solution bears little relationship to mathematics, and I do not understand why you expect a mathematician to produce it, rather than anyone else, for the solution is based on reason alone, and its discovery does not depend on any mathematical principle. Because of this, I do not know why even questions which bear so little relationship to mathematics are solved more quickly by mathematicians than by others.
—Leonhard Euler, describing the Königsburg bridge problem
in a letter to Carl Leonhard Gottlieb Ehler, April 3, 1736
