Discussion of Problem 1397. Points GameAde What's the loser's purpose? // Problem 1397. Points Game 19 Feb 2023 13:59 I got a question about the problem description. In other games, the losers hope to last the game longer for as many turns/rounds/moves as possible. In this game, is the losers' optimal move to (1) to minimize the difference, (2) to maximize theirselves' scores, or (3) to minimize the opponents' scores? Or are the 3 goals lead to the same move? Thanks. hmcab Bad interpretation // Problem 1397. Points Game 4 Jul 2019 18:44 Why the second difference is 1.937 and no 2.000? Kostya python - runtime error test 1 // Problem 1397.

Chmel_Tolstiy Was happy to solve, but much interesting understanding why it'is right. [-] // Problem 1397. Points Game 6 Jul 2008 02:24 crdp To admins: Time Limit in Java [3] // Problem 1397. Points Game 19 Sep 2007 22:47 I have sent two solutions: one in Java, one in Pascal. Java solution is more efficiently. But Java solution got TL1, and Pascal solution got AC. For optimization, i killed making instances of all classes in Java, but still TL1. Can You change java time limit for this problem? Sandro (USU) Re: To admins: Time Limit in Java [2] // Problem 1397. Points Game 19 Sep 2007 23:54 There is no possibility to set different TL for different languages in Timus Online Judge. Your Java solution works more than 5 seconds on 1st test. Write more effective solution. By the way, try to avoid Math.hypot in your program; sqrt works faster. crdp Re: To admins: Time Limit in Java [1] // Problem 1397. Points Game 20 Sep 2007 14:25 Thanks. But I think, that this situation is unfair for Java-programmers. Vladimir Yakovlev (USU) Re: To admins: Time Limit in Java // Problem 1397. Points Game 20 Sep 2007 15:17 Change Math.hypot to Math.sqrt and you'll get 20x acceleration! Solution will work even faster than your pascal solution. So, this problem can be solved in Java with the same algorithm. EfremovAleksei N^2 * <test cases>? it tl #1? why? [2] // Problem 1397.

Simonenko Vladislav Re: any ideas? // Problem 1397. Points Game 26 Sep 2006 20:04 Yeah... CBOSS first contest was based on tasks from Ukrainian ACM. Hint: Look at some greedy algo.
