Project: WEEKLY PUZZLE FUN (wpfB)

Part 1: 7x7 difficult logic-grid puzzle

Objective

To apply your skills in the solving of a logic puzzle.

What you'll likely encounter is that there will be more indirect clues (ie knocking something out directly from a clue in one area, which can have secondary elimination moves elsewhere on the grid). Some of the existing puzzles have aspects like this, but may not have as heavily utilized them as central means to solving the puzzle.

Remember, keeping track of what has been eliminated is just as important as tracking what has been identified. A lot of trouble or dead ends emerged when people were not keeping full inventory on grid box eliminations.

Puzzle Backstory

An environmental impact conference is being held this month in Pasadena, where a different presentation will be made each day. Match each presenter to their topic and institution, and determine the day on which each will give their talk.

Puzzle

Clues

  1. The solar energy expert is scheduled 3 days after the sulfur oxide expert.
  2. Bridget is scheduled 1 day after the presenter from Brown.
  3. Neither the presenter who will speak on May 16th nor the presenter who will speak on May 14th will be the global warming expert.
  4. The acid rain expert is scheduled sometime after the nitrogen usage expert.
  5. The global warming expert is scheduled 2 days after Oliver.
  6. The person who will speak on May 16th isn't from Cornell.
  7. Gerard won't be speaking on May 15th.
  8. The presenter from Stanford will discuss wind power.
  9. Ramon will speak on May 16th.
  10. The person who will speak on May 12th is from Duke.
  11. The presenter from Yale is scheduled 2 days after the presenter from Brown.
  12. Of the presenter who will speak on May 13th and Nancy, one will discuss fossil fuels and the other is from Brown.
  13. Kristen is scheduled 1 day before the person from Ohio State.
  14. The person from Harvard will be either Oliver or the person who will speak on May 10th.
  15. Nancy is scheduled 1 day after Kristen.

Part 2: Word Math Puzzle

Objective

Logic grids are not the only form of logic puzzle; here is another one that relies heavily on logic and reasoning in order to sift through.

A word math puzzle is one where the numbers 0-9 have been replaced with various letters of the alphabet; it is your task to determine what number each letter maps to, and report that to me in the project submission.

For this sort of problem, you will likely want to take notes; all the various little tests you concoct to prove or disprove some relationship. This may also take a bit longer and seem more overwhelming, but really, it is just longhand math :) Remember to attack the problem in pieces, and not head-on all-at-once.

Practice some similar math problems to derive patterns so that the seemingly unfamiliar letters performing math can start to make more sense.

Part 3: Numerical Reasoning

Objective

With the logic grids you put your logic skills to the test, with the word math you math skills. Here, we will explore various other types of puzzles, often combining both logic and math skills to solve, but also exercising different aspects of your deduction/induction skills.

Puzzle

8 6 7
7 8 9 2
9 2 7 3
3 1 5 8
5 1 8 9
2 5 8 7
4 6 5
6 9 8 4

Enter numbers into the blank spaces so that each row, column and 3×3 box contains the full sequence of numbers 1 to 9.

Top row:

pos #0 pos #1 pos #2 pos #3 pos #4 pos #5 pos #6 pos #7 pos #8
5 9 4 7
