PT 51 LG #2

Postby kpuc » Tue Sep 21, 2010 11:31 pm

This game took me about 10 minutes to finish, which bothered me since there were only 5 questions in the game.

This is the one about the expensive hotels. I found it tough because it didn't have many set rules, and had a couple of big conditionals. I ended up having to use hypotheticals a lot, which can take up some time.

Does anyone have a better way to solve a game like this?

Yup, it's easy to get lost in all the conditional rules for this game. I think a very good, if not in fact the best, starting point is to set up the last rule first. There are 2 possible starting points here:

1) H > F > G
2) G > F > H

Once you've established these 2, you can then plug in the 2nd and 3rd rules. In the second rule, G is more expensive than H, which applies to no. 2 but cannot apply to no. 1. In the 3rd rule, H is more expensive than G, which applies to no. 1, but cannot apply to no. 2.

Finally, just plug in the 1st rule as is. Voila! You have your templates.

Thanks! This will hopefully make me less afraid of 3-variable conditionals.

Yep, this is somewhat similar to LG 4 in PT 53 (Debate Team), where once you've set up the 3 possible orders of finishes, you can just plug in the rest of the rules and easily set up your templates.
