| Clarification needed. | Mickkie | 1383. Flower-garden Designs | 22 Sep 2019 20:01 | 1 |
I have 2 questions.
1. As AI Cash asked, can each design have two or more points with the same location?
2. "the pre-jury wants to find the designs which only differ in rearrangement of points and their affine transformation that doesn't change the orientation" does it mean that two designs (P1, P2, P3, ..., Pm) and (Q1, Q2, Q3, ..., Qm) will be considered same if there is an affine transformation Qi=A*Pi+b for all i such that A is matrix 2x2 that detA>0 ?
Thank you from Thailand. :)

| Can there be equal points in one design? | Al.Cash | 1383. Flower-garden Designs | 7 Jul 2009 15:01 | 1 |
If we consider them as flowers then logically it can't be.
But it isn't said explicitly in statement. |

Walrus, CoSec, melody, Safe Bird, please, give me any hint. My e-mail - Ilya[pnt]Grebnov[at]mail[pnt]ru |
| Checking over. Rejudge soon:) | Safe Bird | 1383. Flower-garden Designs | 28 Nov 2005 14:53 | 3 |
Valrus, our programs output the same now.
i have checked the cases we got wrong answer before, they must be wrong!
expecting:) |
| Admins! Please, check test #39! Is it correct? | Valrus | 1383. Flower-garden Designs | 18 Nov 2005 16:10 | 9 |
Even i got the correct algorithm to solve it, I still got stuck on case 10.... :(
how could i contact you? mine is zhuzeyuan@hotmail.com To avoid it completely, as far as I got, I must use int128:S... My e-mail is dimatsu@rambler.ru Test order was changed.
Now test 39 is test 10.
I updated old statistics. He is sure the answer is incorrect.
your output is better than mine, while mine is better than standard.
i am sure i have added a checking part to my program.
anyway, i will try to use int128 in the future.

| 2 Admins, plz correct english text. | Ivankov Dmitry | 1383. Flower-garden Designs | 31 Oct 2005 01:48 | 2 |
Not "positively defined" but "with positive determinant" as it is said in russian text, and which is used in correct definition of affine transformation.
For example matrix
-1 3
-2 1
is not positively defined, but has positive determinant. Fixed (-) Vladimir Yakovlev (USU) 31 Oct 2005 01:48 |

Is this output correct for sample input?
