General Instructions

  1. Please review the grading policy outlined in the course information page.

  2. On the first page of your solution write-up, you must make explicit which problems are to be graded for "regular credit", which problems are to be graded for "extra credit", and which problems you did not attempt. Please use a table something like the following

    Problem01020304 0506070809...
    CreditRCRCRCECRC RCNARCRC...

    where "RC" is "regular credit", "EC" is "extra credit", and "NA" is "not attempted" (not applicable). Failure to do so will result in an arbitrary set of problems being graded for regular credit, no problems being graded for extra credit, and a five percent penalty assessment.

  3. You must also write down with whom you worked on the assignment. If this changes from problem to problem, then you should write down this information separately with each problem.


Problems

Required: 6 of the following 8 problems
Points: 16 pts per problem

  1. Having solved the rental car problem, Prof. Curly is continuing preparations for his cross-country road-trip. It's a long drive from Boston to Seattle---he needs tunes. Prof. Curly has decided to burn a CD containing songs from his favorite group, Led Zeppelin. Prof. Curly likes all of Led Zeppelin's songs, but there are far more songs than he can possibly burn onto a single CD, and he has only one CD to spare. Let n be the number of Led Zeppelin songs, and let m be the capacity of Prof. Curly's CD (in seconds). For each Led Zeppelin song i, let li be its length (in seconds). (Clearly n is an integer, and you may assume that m and li are integers as well, if you like.)
