Farid: May be I misundrestood the problem, but there is said that: This process continues until she wins by entering the finish room or dies by running out of energy (or quits in frustration). And when you enters the room 3 you have negative energy(running out of energy). That's why it is hopeless. ...

### Problem of Euler

Hi All!

You are given 8 numbers:a, b, c, d, e, f, g, h and you should find A, B, C, D such that holds:

( a^2 + b^2 + c^2 + d^2 ) ( e^2 + f^2 + g^2 + h^2 ) = ( A^2 + B^2 + C^2 + D^2 )

How to solve it?

Thanks.

Sorry I don't get it! =( It's said that "The vertices for both polygons correspond to the same set of features in the same order" For examle we may have: 1poligon: right ear tip, chin cleft, right eye, nose, left eye, left ear tip, space between front teeth 2poligon: space between front teeth, right...

### 10556 - Biometrics

Hi All!

To solve this problem I used assumption, that two poligons should have same angles between corresponding edges and have the same scale factor for all corresponding edge's lengths.

Does it right?

2konsept: I found one problem in your algorithm (the same problem why standard dinamic doesn't work :( ). For example when you choosing the element i, and have two diferent elements that you can use: i!=n-1 and n-1. If you choose n-1 element then the last element of another(alternative) doll list ha...

2konsept: Your algorithm looks very good. Just a simple dinamic. You genius =). May be you should change step 3. fits( i+1, i-1 ) because the i-1 element may be inside the can( i, j-1 ) /* I mean when you made can(i, j-1) you may be used can(i-1, j-2). */. To solve this problem I used another "baka"...
