给定的是一块可变大小的板，最大大小为5场5场。每个字段都用“ x”填充。如果未用“ x”填充，则用“ o”填充。

给出了每个板的启动状态（请参见下文）。每块棋盘必须打10轮（最大条件下：请参阅下文），并且必须注意x的演变。

一回合的工作方式如下：

1. 每个“ x”扩展到正交边界的字段，但自身消失
2. 每当两个“ x”在一个场上时，它们彼此抵消

每个回合中所有“ x”的演变必须同时发生。例：

    o o o            o x o
    o x o     ->     x o x
    o o o            o x o

在每一轮演变中，您都必须查看电路板是否清空了“ x”。如果不是空的，可能会出现重复的模式。如果情况并非如此，我们将放弃对演化的分析。另外，您必须为每个起始板打印x字段的最大百分比（四舍五入为整数）。

输入：

输入数据可在此处找到（Pastebin）。该数据包含100个起始状态。如前所述，板的尺寸各不相同。行数用从1到5的n表示，其后是仅包含“ x”和“ o”的n行，表示起始模式。电路板的每一行都有1到5个字段。

输出：

必须打印出完整的结果，每个起始板的打印行必须采用以下格式：

    Round {0-10}: {repetition/empty/giveup}, {0-100} percent maximum-fill

例子：

范例1：

    Input: 2       Starting state: x o x
           xox                     x x
           xx

                          Round 1: x x o
                                   o x

                          Round 2: x o x
                                   o x

                          Round 3: o x o
                                   o o

                          Round 4: x o x   -> The pattern repeats:
                                   o x        It is the same as in round 2,
                                              therefore we stop. Maximum fill was
                                              in the starting state with four times 'x'
                                              of 5 fields altogether,
                                              so we have 4/5 = 80 %.

    Output: Round 4: repetition, 80 percent maximum-fill

范例2：

    Input: 1       Starting state: x x
           xx                      

                          Round 1: x x    ->  We already have a repetition, because
                                              the pattern is the same as in the starting
                                              state. The board is always filled 100 %.

    Output: Round 1: repetition, 100 percent maximum-fill

八天后，我将用最少的字符将有效答案标记为获胜者。另外，我将发布100个启动板的正确输出（输入）。

您可以使用自己喜欢的（编程/脚本/任何语言）语言。

编辑：最近的一次编辑后，一个漏洞潜入水中，导致空板的输出错误（测试套件输出正常）。由于Round 0以给定的输出格式仅意味着输入中可以有空板（尽管测试套件中没有板），因此必须修复该错误。快速修复意味着字节数增加（实际上是增加1）-当然不是一种选择。因此，我不得不多打一点高尔夫球。

-p从STDIN读取（加+1计数）运行。由于r替换修饰符，因此需要5.014 。

(@a,%h,$m)=('',map<>=~y/ox\n/\0!/rd,1..$_);for$n(0..10){$_="Round $n: ".($h{$_="@a"}++?repetition:(($.=100*y/!///y/ //c)<$m?$.:$m=$.)?giveup:empty).", $m percent maximum-fill\n";@a=/g/?map{$_=$a[$i=$_];y//!/cr&(s/.//r.P^P.s/.$//r^$a[$i+1]^$a[$i-1])}0..$#a:last}

即

# '-p' switch wraps code into the 'while(<>){....}continue{print}' loop, 
# which reads a line from STDIN into $_, executes '....' and prints contents 
# of $_. We use it to read board height and print current board's result.

# First line reads board's state into @a array, a line per element, at the same 
# time replacing 'o' with 'x00', 'x' with '!' and chomping trailing newlines. 
# '!' was chosen because it's just like 'x01' except 5th bit (which is not important)
# but saves several characters in source code.

# Note: array is prepended with an empty line, which automatically remains in this 
# state during evolution, but saves us trouble of checking if actual (any non-empty)
# line has neighboring line below.

# %h hash and $m hold seen states and maximum fill percentage for current board,
# they are initialized to undef i.e empty and 0.

(@a,%h,$m)=('',map<>=~y/ox\n/\0!/rd,1..$_);

# /
# Then do required number of evolutions:

for$n(0..10){

# Stringify board state, i.e. concatenate lines with spaces ($") as separators.
# Calculate fill percentage - divide number of '!' by number of non-spaces. 
# Note: using $. magick variable automatically takes care of rounding.
# Construct output string. It's not used if loop gets to next iteration. 
# Check if current state was already seen (at the same time add it to %h) 
# and if fill percentage is 0.

$_="Round $n: "
    .($h{$_="@a"}++?repetition:(($.=100*y/!///y/ //c)<$m?$.:$m=$.)?giveup:empty)
    .", $m percent maximum-fill\n";

# /
# Next is funny: if output string contains 'g' (of 'giveup' word), then evolve 
# further, otherwise break-out of the loop.

    @a=/g/
        ?map{

# Do evolution round. Act of evolution for a given line is none other than 
# XOR-ing 4 strings: itself shifted right, itself shifted left, line above, line 
# below. Result of this operation is truncated to original length using bitwise '&'. 
# Note, when shifting string right or left we prepend (append) not an ascii-0, 
# but 'P' character. It's shorter, and 4th and 6th bits will be annihilated anyway.

            $_=$a[$i=$_];
            y//!/cr
            &(s/.//r.P
            ^P.s/.$//r

C＃-1164个字符

这是我第一次参加代码高尔夫，所以请放纵;-)

我知道，我距离最佳结果还差得很远-顺便说一句，真是太神奇了！

但是我以为我还是会用C＃分享我的解决方案。

using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Net;class Program{static void Main(string[] args){new WebClient().DownloadFile("http://mc.capgemini.de/challenge/in.txt",@"D:\in.txt");var a=File.ReadAllLines(@"D:\in.txt");int l=0;while(l<a.Length){int n=Int32.Parse(a[l]);var b=a.Skip(l+1).Take(n).ToArray();var f=new List<string[]>{b};var d=0;string g=null;while(d<10){var s=f.Last();if(s.All(e=>e.All(c=>c=='o'))){g="empty";break;}var h=new string[n];for(int r=0;r<n;r++){var k="";for(int c=0;c<b[r].Length;c++){int x=0;try{if(s[r][c-1]=='x')x++;}catch{}try{if(s[r][c+1]=='x')x++;}catch{}try{if(s[r-1][c]=='x')x++;}catch{}try{if(s[r+1][c]=='x')x++;}catch{}k+=((x%2)==1)?'x':'o';}h[r]=k;}d++;f.Add(h);var w=false;for(int i=0;i<f.Count-1;i++){var m=f[i];if (!h.Where((t,y)=>t!=m[y]).Any())w=true;}if(w){g="repetition";break;}}if(d==10&&g==null)g="giveup";File.AppendAllLines(@"D:\out.txt",new[]{string.Format("Round {0}: {1}, {2} percent maximum-fill",d,g,f.Select(z=>{int t=0;int x=0;foreach(var c in z.SelectMany(s=>s)){t++;if(c=='x')x++;}return(int)Math.Floor((double)x/t*100);}).Concat(new[]{0}).Max())});l=l+n+1;}}}

仅using指令已包含97个字符-因此，我认为要在200个字符以内实现其余字符将非常困难。

这是一个相当迭代的方法，在许多地方都使用了LINQ。我还包括下载输入文件并将输出文件写入代码中。

该$:部分使主体在输入上递归（J解析时非常不方便的形式），并@在每个部分上应用了菊花链。nlines查找下一板的行数。

每块棋盘（evolvex）上的动作都很简洁：（在高尔夫球中iterate称为a）构造模拟的每个迭代的列表，直到我们击中之前看到的东西或太多步骤为止。然后percent@,.计算每个结果中实心正方形的百分比，然后format运行一些统计数据（在高尔夫球中stat称为t），以弄清楚模拟是如何结束的，哪个百分比最大，依此类推，然后再将所有这些格式化为字符串。

最后，}:在; joinln将所有单个板的输出连接到一个以换行符分隔的字符串之前，要处理一些垃圾。
