## Discussion of Problem 1299. Psylonians

Posted by nikonoff (ONPU) 20 Jan 2009 15:03
We have some mismatch in english and russian versions of problem statements:

1.1.
According to the “Defense” pattern, robot’s actions are defined as follows: calculate the number of enemies and multiply it by 20. If the result is __( greater )__ than the amount of ammunition units left, the robot will “Retreat and Return Fire”. Otherwise, it will act as if following the “Guard” pattern.
1.2.
При реализации модели поведения «защита», робот действует так: если количество врагов умноженное на 20 __( не меньше )__ количества единиц вооружения робота, то робот отступает отстреливаясь. Иначе он действует согласно стратегии «охрана».

2.1.
Similarly, when the battle-robot “Advances and Returns Fire”, it checks the angle to the most dangerous enemy. If the angle is 10 degrees or more, or there are no enemies, the robot just moves __( backward )__ or shoots otherwise.
2.2.
«Наступает, отстреливаясь» означает, что если угол до самой опасной вражеской цели меньше 10, то робот делает выстрел. Иначе, или если врагов нет, движется __( вперед )__.

3.1.
None of these integers exceeds __( 100000 )__.
3.2.
Все числа, во входном файле целые и не превосходят __( 1000000 )__.

? What statement ( eng || rus ) should be consider as correct?
Re: to Admins ! incorrect statement
I think, the English one. At least when I solved this problem, solution written on the basis of russian statement was getting WA because of (1.2)

1 and 2: the correct statement is the Russian one. We apologize to all programmers who solved this problem using the English statement. We added some tests that should have different answers according to the old English and Russian statements, so some authors got WA on them. Now the English statement should be OK. If you find more mistakes, please, write about them.

3: all integers in fact are no greater than 1000. This limitation has been updated in both Russian and English versions.
