“Reasonable’’ collaboration is permitted, but you should not just copy someone else’s solution or look up a solution from an outside source. We will (subjectively) indicate the difficulty level of each problem as follows:
[1] easy
[2] moderately difficult
[3] difficult
[4] horrendously difficult
[5] unsolved
Further gradations are indicated by + and -; e.g., [3-] is a little easier than [3]. A rating of [5-] denotes an unsolved problem that has received little (if any) attention and may not be difficult.
