PQRST 01 - Puzzle Competition has started.
You have seven days to send answers and ratings.

Have a nice week.

[groza528]

Puzzles printed and I'm about to start.
From this website you can expect a lot of high scores, I expect.

[cihanaltay]

I know. And if there exist lots of people sharing
the first place, I will prepare much more distinguishing
optimization puzzles for the next PQRSTs.

[groza528]

A few questions:
1. These are graded by hand (rather than computer), right? If not, what do I do about finding multiple answers?
2. Puzzle 6: Can we push more than one neighbor (i.e. could we choose to push the third row from the bottom to the left?)
3. P6: Does there have to be an empty space behind the piece we push? (In the example, could we have pushed D-right?)
4. P6: Can we push pieces off the board? (In the example, could we push D-left?)
5. [gloat disguised as a question]Any bonus for finishing in under 24 hours?[/gdaaq]
6. Do we rate each puzzle individually, or do we give exactly one 10, exactly one 9, etc?

[groza528]

I fear the answer to question 5 will be, "Yes, you get harder questions next time."

[cihanaltay]

1. Yes, they are checked manually.
2. Puzzle says, a piece can only move one square R or L, and can only push the neighbouring piece on his way, not the ones above or below it (and of course not the one on the opposite way). This rule is naturally true for a pushed piece.
3. No. (You could slide D right in the example)
4. No. (No way)
5. It would be unfair. And, yes, you will surely get harder puzzles next time. : )
6. Individually (10 being top). (I was afraid to get this question)

[CrystyB]

could we send explanations too (in the comment textarea)? Or would it be too time-consuming to look at all of the submitted reasons?

[groza528]

CrystyB: I think if you get a correct answer he will infer that you did it correctly, so an explanation is unnecessary. If you think one or two puzzles have particularly confusing solutions I don't think it would hurt to explain. You may want to wait for an official answer to that question, but that's my take on it.

[cihanaltay]

You don't have to send explanations of your answers.
I won't tell anything about your answer's correctness in this week. You will see your point when the results are posted.

[cihanaltay]

Please send your specific questions to the competition e-mail address:
pqrst@otuzoyun.com

On the other hand, I'll continue to answer general questions.
Thank you GL Forum.

[CrystyB]

I think you missunderstood Groza's #2. Could the Z in row 3 be moved left?

((And i really hate the way i should submit the answer for Puzzle6. I mean how are you to know what Letter i moved?))

What should i rate? Only the IDEA of the puzzles or i should include the impression of the presentation of the puzzle? (i mean verbal, not graphical)

[cihanaltay]

Groza's #2: Yes, the Z in row 6 from the top can be moved left.

Puzzle 6: Yes, it turned out to be hard for me to check the answer keys for puzzle 6. But you can be sure that I'll know.

Ratings: If I would choose one of your two, it would be the IDEA. Of course, there are people rating some puzzles on their presentation.
In general, you should rate them considering FUN while you are solving them, and your REACTION when you first saw them. (I would say ORIGINALITY, but there are some classic puzzles in the test)

Thank you GL Forum.

No need to thank us, we're just doing our job. Whenever there's a puzzle out there that needs to be solved, it is our duty and our privilege to solve it as well as we can.

[groza528]

w00t, time's up!
*anxiously awaits results*

[cihanaltay]

Yes, I'm a results-statistics-fan, too.

I hope I can finish it up in 24 hours.

[UnheardVoice]

It's already over?
*wished he had less homework*

[Da5id]

Crap, I haven't even had a chance to look at them yet. 7 days? Bah.

[cihanaltay]

24-hours was enough to check the results.
But, there are some works to do.
So, wait another 24 or 48.

[cihanaltay]

Results, finally.

[mathgrant]

I'm glad I didn't enter. The answer key seems confusing and inconvenient for geometric puzzles! And how does knowing the perimeter of a shpae show that we know what the shape is for puzzle 03? I must critcize the thought!

[cihanaltay]

You are, of course, right; knowing the perimeter doesn't show knowing the shape. But I hear complaints about the complexity of the answer keys, too.
Actually, I made a mistake by not including a penalty for that puzzle.
On the other hand, there weren't many guesses (That doesn't make the puzzle perfectly fair, though).

And, I would prefer you enter the competition.

[CrystyB]

couldn't you please make a 12-columned table to enable me to see what puzzles i DID solve (and got the max possible)?

Edit: In fact i'd like to know MY scores for each puzzle at least! i think i only got #5 wrong...

[This message has been edited by CrystyB (edited 04-23-2002 09:35 PM).]

[sodasipper]

I also feel my score is rather low compaired to some of the highest score, even though all my answers either matched what you have exactly, or were more, shall we say, creative in obtaining a different answer.

I think a chart showing who got what right would be great. )

[cihanaltay]

A big table with lots of info means lots of work.
But I'll try to post another table directly taken from my excel work.
In this time you can send an e-mail to me asking your scores if you think I miscalculated your points.

[groza528]

my score looks right, but my name is 'Jason' Boomer. Not that worried about it though, don't bother changing it unless you're editing something anyway. When I first saw it I said 'whoa, my dad answered these too?'

------------------
Just listen to the voices. -rlp

[cihanaltay]

I changed it yesterday already.
I'm good at guessing the fathers' names

[cihanaltay]

I've posted the detailed results, in case you are interested:

[Sami]

I'm trying to figure out why you thought my solution to #1 was wrong...

[HappyMutant]

No reflections were allowed. I missed that - bah.

On the first police officers puzzle, could the officer only see one intersection away?

I didn't get last.

- Matt Elder, 50th in PQRST 1

[HappyMutant]

Oh - and one other thing - thanks for putting together the competition. I certainly enjoyed it.

[cihanaltay]

No, there was no restriction on the "Police Officers".
And, note that the instruction was:
"Position three police officers so that any point on any street can be seen by at least one officer."

Thanks GL competitors.
