这个游戏背后的数学/计算原理是什么?

我的孩子们有这个有趣的游戏叫Spot It!游戏限制(我能说的最好)是:

  • 这是一张55张卡片
  • 每张卡上有8张独特的图片(即一张卡不能有2张相同的图片)
  • 鉴于从牌组中选择的任何2张牌,只有1张,只有1张匹配的图片
  • 匹配的图片在不同的卡片上可能会有不同的缩放比例,但这只会让游戏变得更难(即小树仍然与更大的树匹配)

游戏的原则是:翻转2张牌,无论谁先挑选匹配的图片都能获得一分。

以下是澄清的图片:

spot it

(例如:你可以从上面的2张牌看到匹配的图片是绿色恐龙。在右下角和中右图之间,它是一个小丑的头。)

我正在尝试理解以下内容:

  1. 满足这些标准所需的最小不同照片数量是多少?您如何确定?

  2. 使用伪代码(或Ruby),如何从N个图片阵列中生成55张游戏卡(其中N是问题1中的最小数字)?

  3. 更新

    图片确实每张纸牌发生两次以上(与某些人猜测的相反)。查看3张卡的图片,每张卡都带有闪电:3 cards

有限投影几何

axiomsprojective (plane) geometry与欧几里德几何略有不同:

  • 每两个点只有一条线穿过它们(这是相同的)。
  • 每两行恰好在一点上相遇(这与Euclid有点不同)。

现在,将"finite"添加到汤中,您就有了问题:

我们的几何体只有2个点吗?有3分? 4?有7?

关于这个问题仍有待解决的问题,但我们知道这一点:

  • 如果存在Q点的几何图形,则Q = n^2 + n + 1n称为几何图形的order
  • 每一行都有n+1分。
  • 从每一点开始,准确传递n+1行。
  • 总行数也是Q

  • 最后,如果n是素数,那么确实存在一个订单n的几何。


有人可能会问,这与谜题有什么关系。

card代替pointpicture而不是line,公理成为:

  • 每两张卡片只有一张共同的图片。
  • 对于每两张图片,只有一张卡片同时包含这两张图片。

现在,我们来n=7order-7有限几何与Q = 7^2 + 7 + 1。这会使Q=57行(图片)和Q=57点(卡片)。我猜拼图制造商认为55是圆形数字而不是57,剩下2张卡片。

我们也得到n+1 = 8,所以从每个点(卡片)开始,8行通过(出现8张图片),每行(图片)有8个点(出现在8张卡片中)。


以下是从Fano Plane复制的最着名的有限投影(阶2)平面(几何)的表示,其中包含7个点,称为Noelle Evans - Finite Geometry Problem Page

我正在考虑创建一个图像来解释如何将上面的2阶平面与7张卡片和7张图片组成一个类似的拼图,但是来自math.exchange双胞胎问题的链接正是这样一个图表:<强> Dobble-et-la-geometrie-finie

因此, k = 55 卡中包含 m = 8 图片,每张图片来自 n 图片总计。 我们可以重申“我们需要多少张图片 n 这样的问题,这样我们就可以构建一组 k 卡片,在任何一对卡片之间只有一张共享图片?”等同地问:

  

给定一个 n 维度向量空间和所有向量的集合,其中包含等于一个的所有其他零 m 元素,有多大n ,以便我们可以找到一组 k 向量,其成对点积等于 1

确实( n 选择 m )可能的向量来构建对。所以我们至少需要足够大的 n 以便( n 选择 m )&gt; = k 。这只是一个下限,因此为了实现成对兼容性约束,我们可能需要更高的 n

仅仅为了实验,我写了一个小的Haskell程序来计算有效的卡片组:

编辑:我在看到Neil和Gajet的解决方案后才意识到,我使用的算法并不总能找到最佳解决方案,因此下面的所有内容都不一定有效。我会尽快更新我的代码。

module Main where

cardCandidates n m = cardCandidates' [] (n-m) m
cardCandidates' buildup  0  0 = [buildup]
cardCandidates' buildup zc oc
    | zc>0 && oc>0 = zerorec ++ onerec
    | zc>0         = zerorec
    | otherwise    = onerec
    where zerorec = cardCandidates' (0:buildup) (zc-1) oc
          onerec  = cardCandidates' (1:buildup) zc (oc-1)

dot x y = sum $ zipWith (*) x y
compatible x y = dot x y == 1

compatibleCards = compatibleCards' []
compatibleCards' valid     [] = valid
compatibleCards' valid (c:cs)
  | all (compatible c) valid = compatibleCards' (c:valid) cs
  |                otherwise = compatibleCards'    valid  cs

legalCardSet n m = compatibleCards $ cardCandidates n m

main = mapM_ print [(n, length $ legalCardSet n m) | n<-[m..]]
  where m = 8

m 的最大兼容卡数量=每张卡8张图片,可供 n 选择不同数量的图片 n 看起来像这样:

由于组合爆炸,这种蛮力方法并没有走得太远。但我认为它可能仍然很有趣。

有趣的是,似乎对于给定的 m k 随着 n 的增加而增加到某个 n 之后它保持不变。

这意味着,对于每张卡的每个图片数量,可以选择一定数量的图片,这样可以获得最大数量的合法卡片。添加更多图片以从过去的最佳数字中进行选择不会进一步增加合法卡的数量。

前几个最佳 k 是:

对于那些无法用57个点描绘投影平面几何体的人来说,有一个非常好的,直观的方法来构建57张牌和57个符号的游戏(基于Yuval Filmus的答案{{3 }}):

  1. 对于包含8个符号的卡片,请创建7x7独特符号网格。
  2. 为0到6的“斜坡”添加额外的8个符号,加上一个用于无限斜率。
  3. 每张卡片都是网格上的一条线(7个符号)加上一条符号,该符号来自为该线条的斜率设置的斜率。线具有偏移(即左边的起点)和斜率(即,每个步骤右边有多少个符号)。当线条离开顶部的网格时,重新进入底部。请参阅此示例图(来自this question的图片)以获取两张此类卡:
  4. boardgamegeek

    在这个例子中,我采用斜率为零(红色)的一条线和一条斜率为1的线(绿色)。它们恰好在一个共同点(猫头鹰)相交。

    此方法可确保任意两张卡只有一个共同的符号,因为

    1. 如果斜率不同,则线条将始终恰好相交一个点。
    2. 如果斜率相同,则线条不会相交,并且网格中没有共同的符号。在这种情况下,斜率符号将相同。
    3. 通过这种方式,我们可以构建7x7卡(7个偏移和7个斜率)。

      我们还可以通过网格从垂直线构建另外七张牌(即每列)。对于那些,使用无限斜率图标。

      因为每张卡由网格中的七个符号和一个“斜率”符号组成,我们可以创建一个附加卡,它只包含所有8个斜率符号。

      这给我们留下了7x8 + 1 = 57张可能的牌,7 x 7 + 8 = 57张所需的牌。

      (当然,这仅适用于素数大小的网格(例如n = 7)。否则,如果斜率是网格大小的除数,则不同斜率的线可以具有零个或多个交点。)

答案 3 :(得分:9)

其他人已经描述了设计的一般框架(有限投影平面),并展示了如何生成素数阶的有限投影平面。我想填补一些空白。

可以为许多不同的阶数生成有限投影平面,但在素数阶p的情况下,它们最直接。然后,模p的整数形成一个有限域,可用于描述平面中点和线的坐标。点数有3种不同的坐标:(1,x,y)(0,1,x)(0,0,1),其中xy可以采用0的值到p-1。 3种不同的点解释了系统中点数的公式p^2+p+1。我们还可以描述具有相同3种不同坐标的线:[1,x,y][0,1,x][0,0,1]

我们通过坐标的点积是否等于0 mod p来计算点和线是否发生。例如,点(1,2,5)和行[0,1,1]p=71*0+2*1+5*1 = 7 == 0 mod 7发生,但点(1,3,3)和行[1,2,6]是自1*1+3*2+3*6 = 25 != 0 mod 7以来没有发生事故。

翻译成卡片和图片的语言,这意味着坐标为(1,2,5)的卡片中包含坐标为[0,1,1]的图片,但坐标为(1,3,3)的卡片中不包含坐标[1,2,6]。我们可以使用此程序开发完整的卡片列表及其中包含的图片。

顺便说一句,我认为将图片看作点和卡就像线条一样容易,但点和线之间的投影几何图形存在二元性,所以它确实无关紧要。但是,在下文中,我将使用点卡片和卡片线。

同样的结构适用于任何有限的场。我们知道有一个有限的秩序q,当且仅当q=p^k是一个主要的力量。该字段称为GF(p^k),代表“Galois字段”。在主要权力案例中,这些字段并不像在素数情况下那样容易构建。

幸运的是,辛勤工作已经在自由软件中完成并实施,即Sage。例如,要获得阶数为4的投影平面设计,只需输入

即可
print designs.ProjectiveGeometryDesign(2,1,GF(4,'z'))

你将获得看起来像

的输出
ProjectiveGeometryDesign<points=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,

14, 15, 20], [16, 17, 18, 19, 20]]>

我将上述内容解释如下:有21张标记为0到20的图片。每个图块(投影几何图形中的线条)告诉我哪些图片出现在卡片上。例如,第一张卡片将包含图片0,1,2,3和20;第二张卡片上有0,4,8,12和16张图片;等等。

我刚刚找到了用57或58张照片做的方法,但是现在我头痛得很厉害,我会在睡了8到10个小时后发布红宝石代码!只是暗示我的解决方案每7张卡共享相同的标记,并且可以使用我的解决方案构建总共56张卡。

这里是生成ypercube正在讨论的所有57张卡片的代码。它只使用了57张图片,对不起,我已经编写了实际的C ++代码,但知道vector <something>是一个包含something类型值的数组,很容易理解这段代码的作用。此代码使用P^2+P+1张照片生成P^2+P+1张卡片,每张照片包含P+1张照片,并且每张素数P值共享一张共同的照片。这意味着我们可以使用7张照片,每张照片有3张照片(p = 2),13张照片使用13张照片(p = 3张),31张照片使用31张照片(p = 5张),57张牌照57张照片(对于p = 7)等等......

使用z3定理证明器

P为每张卡片的符号数。根据{{​​3}}和ypercubeᵀᴹ的回答,分别有N = P**2 - P + 1张卡片和符号。一副牌可以用其入射矩阵表示,每个卡有一行,每个可能符号有一列。如果卡(i,j)上有符号1,则其i元素为j。我们只需要考虑这些约束来填充这个矩阵:

  • 每个元素都是零或一个
  • 每行的总和正好是P
  • 每列的总和正好是P
  • 任何两行必须只有一个共同的符号

这意味着N**2变量和N**2 + 2*N + (N choose 2)约束。对于小输入,z3似乎可以在不太长的时间内进行管理。

编辑:不幸的是,对于这种方法,P = 8似乎太大了。我在14小时的计算时间后杀了这个过程。

答案 8 :(得分:2)

我写了article关于如何使用Perl中的代码生成这种类型的套牌。代码没有经过优化,但它至少能够生成“合理”订单的套牌......还有更多。

这是一个8阶的例子,它必须考虑稍微复杂的基础数学,因为8虽然是生成这类甲板的有效顺序,但不是素数。如果您只想生成稍微困难的Spot-It,请参阅上文或文章以获取更详细的说明: - )

072的每个标识符都可以作为卡标识符和图片标识符读取。例如,最后一行表示:

  • 72包含图片21322,...,5968,和
  • 图片72出现在卡21322,...,5968中。

答案 9 :(得分:0)

我编写了以下代码来计算卡片。这个想法是创建第一张带有 n 个图像的卡片。如果每对图像索引的差异是唯一的,则可以通过使用相同的值增加每个索引以模 m = n * n - n + 1 来简单地生成其余的卡片

static public int[] Backtrack(int n)
        {
            int m = n * n - n + 1;
            int[] Check = new int[m];
            int C = 1;
            int[] T = new int[n];
            int _p = 2;
            T[1] = 1;
            if (n > 2) T[2] = 1;
            else return T;
            while (_p >= 2)
            {
                T[_p]++;
                if (T[_p] == m)
                {
                    _p--;
                    continue;
                }
                bool good = true;
                C++;
                for (int i = 0; i <= _p; i++)
                {
                    for (int j = 0; j < i; j++)
                    {
                        int x = (T[i] - T[j] + m) % m;
                        if (Check[x] == C || Check[m - x] == C)//x cannot be equal to m-x as m is odd.
                            good = false;
                        Check[m - x] = C;
                        Check[x] = C;
                    }
                }
                if (good)
                {
                    _p++;
                    if (_p == n)
                    {
                        _p--;
                        return T;
                    }
                    T[_p] = T[_p - 1];
                }

            }
            return new int[] { };
        }
        static void Main(string[] args)
        {
            for (int N = 2; N < 11; N++)
            {
                var X = Backtrack(N);
                if (X.Length > 0)
                {
                    int K = N * N - N + 1;
                    Console.WriteLine("Cards: {0} Order {1}:", K, N - 1);
                    int C = 0;
                    for (int j = 0; j < K; j++)
                    {
                        Console.Write("Card {0:000}:", C++);
                        for (int i = 0; i < N; i++)
                        {
                            var t = (X[i] + j) % K;
                            if (j != 0 && Array.Exists(X, x => (x == t)))
                                Console.ForegroundColor = ConsoleColor.Green;
                            Console.Write("\t{0}", t);
                            Console.ResetColor();
                        }
                        Console.WriteLine();
                    }
                }

            }
        }
