帮我认出我的怪物

Question

背景

计算机游戏NetHack起源于1987年，当时在计算机游戏中广泛使用图形。游戏中有很多怪物，而且可能需要同时在屏幕上放很多东西，所以怪物是以极小的方式画出来的:一个怪物只是在屏幕上画一个ASCII角色。

除了有很多怪物，还有很多类型的怪物。重要的是要知道哪个是哪个，当你看到一只小猫和一条龙时，你的反应可能会有所不同。因此，ASCII的大部分用于表示怪物；例如，一只小猫是f，而红色的龙是D。这意味着，它可以非常有帮助地知道一个给定的怪物将是什么样子，因为它将帮助你认识它，如果你遇到它在稍后的游戏。(请注意，怪物的种类多于ASCII字符，因此其中一些字符是共享的；红龙和蓝龙都是D。)

任务

您的程序必须以NetHack怪物的名称作为输入，并生成游戏中表示它的ASCII字符作为输出。允许程序假定输入实际上是NetHack怪物的名称；如果它希望崩溃，如果输入无效，它可能产生毫无意义的结果等等。

下面的Stack代码段是一个JSON对象，它将可能的输入完全映射到相应的输出：

因此，这里的任务基本上是“给定由上面的JSON对象表示的字典中的一个键，返回相应的值”。

注意，在某种程度上，这个挑战是一个反向的kolmogorov-复杂性；不是从一个小/空输入转到一个大输出，而是从一个大输入转到一个小输出。(因此输入中有大量冗余信息，您可以随意忽略或使用这些信息)。它也非常类似regex高尔夫，只是a)允许任何语言(不仅仅是regex)，和b)有两个以上的可能的输出。(我们以前有过一些类似的任务，比如这些 二，但是这个任务有点不同，因为指定的输入/输出行为有更强的模式)。

Clarifications

您可以使用任何合理的输入和输出格式(例如，您可以将输出作为字符、其ASCII代码或一个字符长的字符串)。如果您愿意，可以提交函数而不是完整的程序。

在标准漏洞中已经提到了这一点，但只是想重申一句:除了程序的源代码之外，您不能在任何地方存储输入和输出之间的通信。这一挑战基本上是关于在尽可能小的空间内表示输入/输出行为，因此您不能从互联网下载列表、将通信存储在外部文件中、在调试模式下启动NetHack并生成所讨论的怪物来查看它的外观等等。(此外，我也不想为了测试你的作品而与怪物搏斗。)

胜利条件

这是密码-高尔夫，所以获胜的条目将是最短的条目，以字节计。祝好运!

        int i, j, k, c, d, h = u[0].hashCode(),

        char r = '@';
        for (i = 0, k = 0; i < 4297; i += 14) {
            for (c = 0, j = 7; j >= 0; j--)
                c += c + (s.get(i + j) ? 1 : 0);
            if ((k += c) == a) {
                for (d = 0, j = 13; j >= 8; j--)
                    d += d + (s.get(i + j) ? 1 : 0);
                r = d < 5 ? " &':;".charAt(d) : (char) ((d < 31 ? 60 : 66) + d);
            }
        }
        System.out.println(r);
    }
}

怪物的名字是：

• 使用Java hashcode方法=> 32位进行散列
• 带掩码的ANDed 1001001000111111111100 => 13位
• 从最小到最大
• 然后，我们使用排序列表=> 8位的增量值。

所述显示字符编码在6位上。

所以每个元组(怪物名称，字符)使用14位。所有元组都保存在一个BitSet和基64编码。

使用base64编码和BitSet操作，我丢失了很多字节:-)

这是我的测试工具，以防它对其他人有帮助。

MAPPING = {
    # as given in the original question
}
def validate_solution(f):
    for k, v in MAPPING.iteritems():
        vv = f(k)
        if vv != v:
            print 'FAIL: f(%s) = %s instead of %s' % (k, vv, v)
    print 'SUCCESS!'

我编写了一个小程序来枚举所有提取4个字符的各种方法以及字符串的长度。我最初的计划是对这些字符进行ord()，对它们进行一些计算，并将其归结为一个完美的哈希函数，该函数将索引生成一个输出表。因此，我编写了另一个小程序来枚举所有将这4个字符相加/乘/模的各种方法；但是产生的散列函数仍然有太多的冲突。最后，我放弃了，只做了你在这里看到的事情，这只是一张从每个怪物名字的小字符串表示到适当的符号的地图。

就是:我想得到的是

def f(monster_name):
    small_string = f1(monster_name)
    integer_index = f2(small_string)
    symbol = "relatively_short_table"[integer_index]
    return symbol

但我只设法做到

def f(monster_name):
    small_string = f1(monster_name)
    symbol = {relatively_large_dict}[small_string]
    return symbol

其中，我的字典查找{relatively_large_dict}[small_string]是表示为re.match(small_string+"(.)", "relatively_large_string")的高尔夫球。
