注意：该挑战目前已死，因为我无法安装运行比赛所需的语言。如果其他人有时间和兴趣去做，我并不反对。

有关排行榜，请参见帖子底部。

这是一种半合作式的“山上之王”挑战，机器人在其中通过二维网格图构建路径。控制流量最大的节点的机器人是赢家。但是，实际上需要一个机器人的资源来建立一条连接路径，因此这些机器人必须在某种程度上协同工作。

游戏玩法

在下面，N > 0设为正在运行的机器人的数量。

网格

游戏在尺寸为2的二维整数网格上进行，其左下坐标为。每个坐标与具有出边的三个坐标，以及在其上方，其中，所述坐标-取模 。这意味着网格在东边和西边环绕。每个下坐标是一个源，每个上坐标是一个下沉。⌊4/3N2⌋ × ⌊4/3N2⌋(0,0)(x,y)0 ≤ y < ⌊4/3N2⌋-1(x-1,y+1)(x,y+1)(x+1,y+1)x⌊4/3N2⌋(x,0)(x,⌊4/3N2⌋-1)

下图显示了一个8 × 8网格。

图的每个顶点是不活动的，活动的或损坏的。所有顶点都开始处于非活动状态，并且可以被漫游器激活，然后漫游器将成为其所有者。此外，漫游器可能会破坏顶点，因此无法修复。

转单

转弯包括破坏阶段和激活阶段。在销毁阶段，每个漫游器可能会破坏一个不活动的顶点。该顶点从那时起就被破坏了，任何人都不能激活它。在激活阶段，每个漫游器可以激活一个不活动的顶点。从那时起，他们拥有该顶点，并且其他任何人都无法重新激活它。如果多个漫游器都在同一转弯上激活单个顶点，则它们可能拥有一个顶点。在每个阶段，顶点选择是同时完成的。

计分

一轮持续一圈。此后，该回合得分如下。从每个活动的源顶点，我们沿着活动的顶点执行一次随机的深度优先搜索（这意味着每个顶点的子级均以随机顺序访问）。如果找到从源到某个汇的路径，则对于该路径上的所有顶点，顶点的每个所有者都会获得一个点。N2N

整个游戏持续100回合，而总分最高的机器人就是赢家。如果分数差异太大，我可能会增加这个数字。

附加规则

• 不会弄乱控制器或其他提交内容。
• 每个参赛者最多提交一份。
• 在游戏开始时，除了一个私人文本文件外，没有其他外部资源被清除。
• 不要设计您的机器人来击败或支持特定的对手。
• 提供命令来编译和运行您的机器人。可以免费使用任何可用于Debian Linux的编译器/解释器。

控制器

该控制器是用Python 3编写的，可以在GitHub中找到。有关详细说明，请参见README文件。这是一个让您入门的API：

• 僵尸程序在每个回合开始时开始，并一直持续到回合结束。使用换行符终止的消息，通过STDIN和STDOUT与控制器进行通信。
• BEGIN [num-of-bots] [num-of-turns] [side-length] 在开始时输入。
• DESTROY [turn]在每个销毁阶段开始时输入。您的漫游器应VERTEX x,y以选择一个顶点或做出响应NONE。
• BROKEN [turn] [your-choice] [other-choices]在每个销毁阶段结束时输入。其他机器人的顺序在每个游戏开始时都是随机的，但在此过程中保持不变。选项显示为x,y或N。
• ACTIVATE [turn]和OWNED [turn] [your-choice] [other-choices]在激活阶段与上述等效，并且具有相同的语义。
• SCORE [your-score] [other-scores] 在游戏结束时输入。
• 您的机器人有1秒的时间来分析阶段的结果并选择下一个顶点，并在给出分数后有1秒的时间退出。我将在相对较旧的笔记本电脑上测试提交的内容，因此最好在此处留一些余量。

请记住刷新您的输出缓冲区。否则可能会使控制器挂在某些环境中。

排行榜

2015年3月13日更新

Peacemaker已启动并正在运行，Funnelweb也收到了更新。分数上升了一个数量级。连接器在两场比赛中超过了时间限制。

Funnelweb: 30911
Connector: 18431
Watermelon: 3488
Annoyance: 1552
Explorer: 735
Checkpoint: 720
Random Builder: 535
FaucetBot: 236
Peacemaker: 80

带有ASCII美术图形的完整日志可以在控制器的存储库中找到graphical_log.txt。

一些观察：

• 通过断开连接器前面的单个顶点，可以很容易地将其停止。我怀疑烦恼经常这样做。但是，这目前意义不大，因为只有连接器才能构想出一条路径。
• 只需碰巧在连接路径上，西瓜就可以得到不错的成绩（因为DFS很可能会使用其顶点）。
• 探险家喜欢用西瓜种藤。
• 更新的Funnelweb得分很高，因为Connector通常会锁定在网格的下半部分。
• 游戏变得相当长，平均回合在我的机器上花费约25秒。

连接器（Java）

尝试在随机位置创建路径。由于它无法自行创建路径，因此它将搜索活动的单元并使用它们。归功于Geobits，我从那里偷了一些代码。此外，此提交尚未完成，因为它会在构建路径后立即停止执行任何操作。

编辑：如果建立了路径，则Connector会尝试沿现有路径创建多个路径。

Funnelweb，Python 2

版本1.2-更好的连接代码，添加了新动画

以澳大利亚不那么友好的蜘蛛之一的名字命名。该漫游器首先在最上面的行中建立一个漏斗形的嵌套，然后诱使其他漫游器进入构建路径以访问该嵌套。

这是4 / 3N ^ 2板上的6 bot游戏的新动画，显示了funnelweb和一些更简单的bot：

Funnelweb的Python代码：

from random import *

    msg = raw_input().split()

Java检查点

该机器人试图创建检查点，以便任何有效路径都穿过我的一个顶点。由于有N ²圈，且板的宽度为² N ²，所以我可以激活/断开一条水平线上的每个节点（假设我先在那里）。以交替模式执行此操作（x已损坏，o是我的）：

xoxoxoxoxoxox...

如果您想走一条路，您需要通过我的检查站:)

现在，这可能会面临几个问题。首先，除非有很多路径，否则根本不会做得很好。由于他自己没有走任何生产性道路，因此他确实完全依赖于一些竞争对手。即使是几个竞争者组合在一起以创建一条单一路径也无济于事，因为他只为找到的每条路径得分。他需要大放异彩的是很多机器人在走很多不同的道路。即使这样，它可能没有得分非常高，但它是一个想法，我在聊天，所以...

如果该行中的一个空格已被阻止/声明，我只是在寻找可以使用的附近地点（最好是在同一x行中，只是垂直移动）。

        print("VERTEX %d,%d"%(r.randrange(side_len), r.randrange(side_len)), flush=True)
    elif msg[0] == "SCORE":
        break

使用命令运行

python3 random_builder.py

根据您的Python安装，您可能需要替换python3为python。为此，只需编辑bots.txt文件。我更新了控制器，不再需要弄乱文件路径。

资源管理器，Python 3

激活策略：

根据每个节点的状态（活动/不活动/损坏）创建一个热图，并选择一个人的期望热图值最大的节点（如果可以选择的话）。

销毁策略：

永远不要破坏任何东西，因为那对机器人没有多大帮助。

中间人

我看到有些机器人是从顶部构建的，有些是从底部构建的。（我认为）这是第一个从中间开始并逐步进行的工作。
