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

To apply your skills in the solving of a logic puzzle. We're going to start with a 4×4 grid size, on the easiest level of difficulty, to aid you in getting started and acclimated to this style of puzzle. Each week there will be a new puzzle with gradually increasing resolution and/or difficulty.

Some things to keep in mind when solving this type of puzzle:

• no selection in any category can be used more than once
• analyzing what is NOT possible can be just as helpful as finding what IS possible
• be mindful of the properties of your basic logical connective words:
  • NOT: typically stating an invalidation
  • AND: identifying a grouping (bread AND butter, indicating the two are paired in some fashion of consideration)
  • OR: for the purposes of these puzzles, the association of various items with the OR connective is typically done in an EXCLUSIVE fashion versus the INCLUSIVE fashion it can also be used as. An EXCLUSIVE OR (XOR) means ONE or the OTHER, but NOT BOTH
• Mark off disproven cells with an X
• For proven cells, some sort of confirmation mark (I like using a small solid circle)
• Some print out the puzzle and complete it in pencil; others load the image into some sort of image/paint program and use the “fill” tool (with two different colors queued up) to complete the puzzle. Either way, you will want to record your resulting associations to report to the submit tool
• From experience, especially with any new or less familiar activity, the more manual you make the process and perform it by hand, the more improvement you will reap over time
• Be sure to cross-reference! Sometimes you'll get “half clues” in one category, which can be linked to an associated “half clue” in another category, enabled further cell eliminations or even derivations of confirmed association
• Be aware of your units, and how they progress; provided clues will often play off the patterned ordering of the units
• Once you have fully exhausted a clue, cross it out to aid you in focusing on the clues that still need resolution

Please do endeavor to put forth original, honest effort in the solving of these puzzles, by hand; the process will help foster and solidify many analytical reasoning skills that will influence and improve your logic and programming skills. Improvements won't happen overnight, but through consistent practice, by the end of the semester you should start reaping the benefits of such an activity.

It is formal night on the top deck of the “Ruby Rose” cruise ship, and a group of long-time passengers are seated at the captain's table, sharing stories of their previous cruises. Match each person to their last cruise destination, determine what year they went, and also what cruise line they booked.

1. Of Kathy and the traveler who went to Jamaica, one took the Farralon cruise and the other was on the 1986 cruise.
2. The traveler who took the Neptunia cruise set sail 1 year after the traveler who went to Barbados.
3. The traveler who took the 1986 cruise is either Ollie or Kathy.
4. The person who took the Farralon cruise set sail sometime after Ollie.
5. The person who went to Aruba set sail 1 year after the person who took the Baroness cruise.
6. Francis is either the traveler who took the 1986 cruise or the traveler who took the 1983 cruise.
