Assignments will mostly be exercises from the textbook, to be handed to me in lectures.
The current plan, subject to change, is to have the assignements handed in on Tuesdays, lecture numbers 9, 14, 20, 28, 33, covering material up to and sometimes including the lecture of the Wednesday a week before the hand-in date.
Assignments will be up at least a week in advance of the hand-in date.
In Ch5 Q10, by "combinatorial reasoning" it means an argument involving counting things, as opposed to the algebraic argument we gave in class. So you should use the characterisation of n-choose-r as being the number of subsets of size r of a set of size n.
("balanced" is the book's terminology for the nim sum being 0)
- Clarification of question 18: when it says "no two rooks attack each other", it means that no two rooks should share a column or a row. The colours aren't relevant to this.
- (See section 2.5 if you don't know about poker; briefly, a poker hand consists of 5 cards from the 52 in a standard deck. a "flush" means all five are of the same suit, a "straight" means that the cards are of five consecutive ranks, with the Ace counting either high or low but not both (no wrap-arounds allowed).)
