--- Day 13: Knights of the Dinner Table ---
|
||||
|
||||
In years past, the holiday feast with your family hasn't gone so well. Not everyone gets along!
|
||||
This year, you resolve, will be different. You're going to find the optimal seating arrangement
|
||||
and avoid all those awkward conversations.
|
||||
|
||||
You start by writing up a list of everyone invited and the amount their happiness would
|
||||
increase or decrease if they were to find themselves sitting next to each other person. You
|
||||
have a circular table that will be just big enough to fit everyone comfortably, and so each
|
||||
person will have exactly two neighbors.
|
||||
|
||||
For example, suppose you have only four attendees planned, and you calculate their potential
|
||||
happiness as follows:
|
||||
|
||||
Alice would gain 54 happiness units by sitting next to Bob.
|
||||
Alice would lose 79 happiness units by sitting next to Carol.
|
||||
Alice would lose 2 happiness units by sitting next to David.
|
||||
Bob would gain 83 happiness units by sitting next to Alice.
|
||||
Bob would lose 7 happiness units by sitting next to Carol.
|
||||
Bob would lose 63 happiness units by sitting next to David.
|
||||
Carol would lose 62 happiness units by sitting next to Alice.
|
||||
Carol would gain 60 happiness units by sitting next to Bob.
|
||||
Carol would gain 55 happiness units by sitting next to David.
|
||||
David would gain 46 happiness units by sitting next to Alice.
|
||||
David would lose 7 happiness units by sitting next to Bob.
|
||||
David would gain 41 happiness units by sitting next to Carol.
|
||||
|
||||
Then, if you seat Alice next to David, Alice would lose 2 happiness units (because David talks
|
||||
so much), but David would gain 46 happiness units (because Alice is such a good listener), for
|
||||
a total change of 44.
|
||||
|
||||
If you continue around the table, you could then seat Bob next to Alice (Bob gains 83, Alice
|
||||
gains 54). Finally, seat Carol, who sits next to Bob (Carol gains 60, Bob loses 7) and David
|
||||
(Carol gains 55, David gains 41). The arrangement looks like this:
|
||||
|
||||
+41 +46
|
||||
+55 David -2
|
||||
Carol Alice
|
||||
+60 Bob +54
|
||||
-7 +83
|
||||
|
||||
After trying every other seating arrangement in this hypothetical scenario, you find that this
|
||||
one is the most optimal, with a total change in happiness of 330.
|
||||
|
||||
What is the total change in happiness for the optimal seating arrangement of the actual guest
|
||||
list?
|
||||
|
||||
Your puzzle answer was 733.
|
||||
|
||||
--- Part Two ---
|
||||
|
||||
In all the commotion, you realize that you forgot to seat yourself. At this point, you're
|
||||
pretty apathetic toward the whole thing, and your happiness wouldn't really go up or down
|
||||
regardless of who you sit next to. You assume everyone else would be just as ambivalent about
|
||||
sitting next to you, too.
|
||||
|
||||
So, add yourself to the list, and give all happiness relationships that involve you a score of
|
||||
0.
|
||||
|
||||
What is the total change in happiness for the optimal seating arrangement that actually
|
||||
includes yourself?
|
||||
|
||||
Your puzzle answer was 725.
|
||||
|
||||
Both parts of this puzzle are complete! They provide two gold stars: **
|
||||
|
||||
At this point, you should return to your advent calendar and try another puzzle.
|
||||
|
||||
