-======Project: 6x6 LOGIC PUZZLE - WEEKLY PUZZLE FUN (wpf2)======
+======Project: WEEKLY PUZZLE FUN (wpf2)======
-=====Objective=====
+=====Part 1: 6x6 easy-level difficulty logic-grid puzzle=====
-To apply your skills in the solving of a logic puzzle.
-=====Puzzle Backstory=====
+====Objective====
-Whistler County just held its annual "Potato Launch" contest, wherein different teams build home-made contraptions and each tries to shoot colored potatoes as far as they can. Using only the clues below, determine each team's best distance (in feet) and match up the type of device each used and the color of the potato they launched.
+To apply your skills in the solving of a logic puzzle. We're going to increase the grid resolution by 1, for a 6x6 grid size, remaining on the easiest level of difficulty.

+Each week there will be a new puzzle with gradually increasing resolution and/or difficulty.
-=====Clues=====
+====Grid-Based Puzzle Strategies====
+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" or indirect clues in one category, which can be linked to an associated "half" or indirect clue in another category, enabling further cell eliminations or even derivations of confirmed association(s)
+  * 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
-  - Of the team that made it to 135 ft and the team that made it to 180 ft, one used the red potato and the other used the vacuum cannon.
+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" have emerged when people were not keeping full inventory on grid box eliminations.
-  - The Russets didn't use the air cannon.
-  - The group that launched the white potato went 30 feet farther than the contestants that used the hybrid sling.
+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.
-  - The contestants that used the trebuchet, the team that used the vacuum cannon, the Super Tubers, the group that used the air cannon and the Mad Mashers were all different teams.
-  - The Super Tubers didn't use the red potato.
+====Puzzle Backstory====
-  - The Spud Chuckers didn't use the air cannon.
+Vikram Allindra has established an orangutan sanctuary in the Borneo rainforest, where injured and abandoned orangutans can be cared for and eventually released back into the wild.
-  - The group that launched the purple potato went 15 feet farther than the team that used the hybrid sling.
-  - The team that launched the purple potato landed 60 feet short of the Potato Bros.
+====Puzzle====
-  - The group that launched the yellow potato landed somewhat short of the group that used the trebuchet.
-  - Of the contestants that used the air cannon and the contestants that used the trebuchet, one scored a distance of 165 ft and the other used the orange potato.
+{{ :haas:fall2017:discrete:projects:wpf2.png |}}
-  - The group that made it to 150 ft didn't use the water cannon.
-  - The Potato Bros didn't use the trebuchet.
+====Clues====
-  - The Russets landed somewhat short of the contestants that launched the orange potato.
+  - The ape that was found in Melak is 12 years older than the orangutan Francine works with.
+  - Ofallo isn't cared for by Beatrice.
+  - Of the animal that was found in Melak and the ape Francine works with, one is Shamir and the other is 4 years old.
+  - The animal that was found in Basahan isn't cared for by Eva.
+  - The 10-year-old isn't cared for by Dolly.
+  - Nikatrice didn't come from Sebulu.
+  - The ape Aldo works with is 12 years older than the animal that was found in Ambalat.
+  - The orangutan Francine works with is 6 years younger than Ofallo.
+  - Of the 13-year-old and the orangutan that was found in Puruk Cahu, one is Rajesh and the other is cared for by Beatrice.
+  - The animal Eva works with, Pemson, Ofallo, the 7-year-old and the animal that was found in Sebulu are all different animals.
+  - Of the animal that was found in Ambalat and the 7-year-old, one is Quirrel and the other is cared for by Francine.
+=====Part 2: Letter Division 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 letter division 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.
+====Letter Division Puzzle Strategies====
+Some things to keep in mind when solving this type of puzzle:
+  * take copious notes
+  * jot down patterns and observations
+  * perform tests to prove or disprove a relationship
+  * look for any "obvious" giveaway clues, like what letters could represent 0, 1, and 9
+  * try to identify the non-borrows, borrows, and "double" borrows, marking them as appropriate
+  * write out relationships so that you can keep track of them, things like:
+    * A < B << C
+      * I use the single less than to denote a direct neighbor (A is one less than B), and the double less than sign to denote general less than-ness (we know that B is less than C, but we do not know how much it is less than C).
+  * use "process of elimination" number sets
+    * I will also write out each letter and all the numbers it could be, erasing eliminated values along the way. Sometimes you will arrive at an association through this method.
+    * For example:
+      * A = { 0 1 2 3 4 5 6 7 8 9 }
+      * B = { 0 1 2 3 4 5 6 7 8 9 }
+        * and so on for each letter. If we were to determine that B is not 9, erase it from B's number set. That way, when we're hunting for possible candidates for 9 (for example), we can directly rule out B
+  * sometimes you can derive important clues from the multiplication aspect of the puzzle (especially finding the occasional dead-ringer for 0 or 1)
+  * don't rely on just one method: use all of these methods. With different puzzles you will find differing levels of values with each method (but in general, I find the more methods I use the easier the overall puzzle becomes)
+As I said: 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 can be important in the bigger picture. This may also take a bit longer and seem more overwhelming (especially at first), 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.
