介绍

在2042年，世界变得人口过多。全球化，人满为患，新的生活方式以及全球缺乏卫生条件导致了新的流行病蔓延。在那些困难时期，国家领导人必须管理局势。您不能让人口大量减少，但也许可以让邻居死掉而受益……

词汇表

健康：人们没有感染
感染：谁可以从大流行死亡人
死亡：尸体数量，没有特别的影响（只计分）
感染率：数健康谁就会成为感染每回合
传染率：百分比感染，将转换健康到被感染每回合
死亡率：每回合将死亡的感染百分率
迁移率：每回合将迁移/迁徙的健康和感染百分率
当地：仅影响您的州
全局：影响每个州

原理

每个参与者将从100个人开始管理一个城镇。不幸的是，其中有一个被感染。

该游戏是回合制的。转弯由七个阶段组成，最后一个阶段是交互式的（向机器人询问命令）。玩家的顺序在每个回合中都是随机的。下一个阶段在每个城镇都执行了上一个阶段时开始（第1轮：玩家1，第2玩家，...；第2轮：第3玩家，第2玩家，第1玩家...）：

1. Mutation                                 - AUTOMATED
2. Reproduction                             - AUTOMATED
3. Migration                                - AUTOMATED
4. Infection                                - AUTOMATED
5. Contagion                                - AUTOMATED
6. Extinction                               - AUTOMATED
7. Players Turn                             - INTERACTIVE

控制器通过命令参数为您提供输入，而程序必须通过stdout输出。

句法

输入值

每次调用程序时，它将收到以下格式的参数：

Round;YourPlayerId;PlayerId_Healthy_Infected_Dead_InfectionRate_ContagionRate_LethalityRate_MigrationRate;PlayerId_Healthy_Infected_Dead_InfectionRate_ContagionRate_LethalityRate_MigrationRate;...

回合均为1索引。

输入示例

6;2;1_106_23_9_2_4_13_5;0_20_53_62_16_20_35_5;2_20_53_62_16_20_35_5

在这里，您看到它是第六轮，您是玩家2。您有20位健康，53位感染，62位死亡，16％的感染率，20％的传染率，35％的致死率和5％的迁移率。

输出量

您必须输出三个字符（无空格，无分隔符），每个字符对应于本轮将要执行的一个动作。字符的顺序决定了动作的顺序。您可以多次输出相同的动作。

N：执行Ñ othing
M：研究中号 icrobiology [效果：减少本地传染率 4％]
E：研究È pidemiology [效果：减少本地传染率 8％]
I：研究我 mmunology [效果：减少本地致死率 4％]
V：研究V预防接种的[效果：减少本地传染率被一个，减少局部传染率 4％，减少局部致死率 2％]
C：给ç URE [效果：转换10局部感染到健康 ]
Q：Q uarantine [效果：移除30个本地感染者 ]
O：O边界[效果：将本地迁移率提高10％]
B：关闭B订单[效果：将本地迁移率降低10％]
T：Bio T错误[效果：转换4全球健康到感染 ]
W：w ^ eaponization [效果：增加全球传染率通过1，增加全球致死率 2％]
D：d issemination [效果：增加全球感染率通过如图1所示，增加全球传染率 2％]
P：P acification [效果：减少全球传染率通过1，减少全球传染率 1％，减少全球致死率 1％]

游戏玩法

所有阶段

无效的命令 =没有
百分比像整数一样累加，即10％-4％= 6％。在公式中应用百分比时，结果将被下限。

阶段1：变异

大流行变得越来越有力。每回合，它随机获得以下属性之一（此突变会同时影响所有玩家）：

• 全球感染率提高2
• 全球传染率提高5％
• 全球致死率提高5％

阶段2：复制

每五轮比赛（第5、10、15轮...）将诞生新的公民。每对健康者将使一个健康者（23个健康者产生11个新的健康者）。每对感染都会造成一个感染。

阶段3：迁移

每回合，根据迁移率的不同，一部分健康和受感染的人将离开州（10个健康人将离开一个州，其健康状况为100 ，迁移率为 10％）。然后，将再次根据移民率在各个州之间分配移民。（对每个州的比率进行加权，然后对移民进行相应分配）。

阶段4：感染

健康每个状态被转换为感染，根据感染率。

阶段5：传染

根据传染率，将每个状态的健康状态都转换为感染状态。数乘以计算出的感染由传染率。

阶段6：灭绝

根据死亡率，感染者会转化为死亡。数乘以计算出的感染由致死率。

阶段7：玩家回合

每个玩家都收到输入，并且必须输出三个动作，这些动作按照输出的顺序执行。

规则

• 不得将Bot写为击败或支持其他特定的Bot。
• 允许写入文件。请写入“ yoursubmissionname.txt”，游戏开始前该文件夹将被清空。禁止使用其他外部资源。
• 您的提交有1秒钟的响应时间（每个镇）。
• 提供命令以编译和运行提交。

获奖

获胜者是50轮后最健康的赢家。如果玩家是最后一位在世（超过0个“ 健康”或“ 感染”），游戏将停止并获胜。如果多个玩家有相同数量的健康，在一个大多数感染会获胜，那么一个用更少的死秒。

控制者

您可以在GitHub上找到控制器。它还包含三个用Java编写的samplebot。
要使其运行，请签出项目并在Java IDE中将其打开。main类方法中的入口点Game。需要Java 8。

要添加机器人，首先需要Java的编译版本（.class文件）或解释语言的源代码。将它们放置在项目的根文件夹中。然后，在players包中创建一个新的Java类（您可以在已经存在的机器人上举个例子）。此类必须实现Player以重写方法String getCmd()。返回的字符串是运行您的机器人的shell命令。例如，你可以让使用此命令红宝石机器人的工作：return "C:\Ruby\bin\ruby.exe MyBot.rb";。最后，将Bot添加players到Game类顶部的数组中。

家庭价值观注重自我保护和防御，并且仅为此目的而采取行动。它使用点值系统来确定最佳操作方案，然后调整其自身的状态值以更好地确定其下一个优先级。如果出现平局，它将从最佳选项中随机选择。

和平主义者非常关注杀戮和死亡，因此认为强大的全球健康意味着强大的本地健康。因此，他们几乎只专注于减少全球疾病，同时保留部分边界以允许善良四处传播。

治愈所有被感染的人，除非只有2个或更少的人，否则它会使美国变得更好。少数群体将被忽略。

更少的感染使这种药物更便宜。

不需要移民-他们只带来感染。

如果什么也没做，那就炸其他玩家。

以美式方式颠倒命令顺序，炸弹先治愈人们。

编辑：修复了垃圾邮件可以治愈的错误，因为治愈后感染人数并未降低。

由调用Rscript AllOrNothing.R。

这里的想法是一方面将感染的最大风险（通过降低感染率，治愈感染者并防止感染者移民）限制到最大，另一方面增加疾病的致死率，使确诊的人被感染，在污染他人之前死亡。

编辑：稍微调整了策略。

军医

军医总是…… 无药可救的人感到困扰。他喜欢练习医学，所以这就是他的全部。他还喜欢python，因此他用Python编写了代码。如果您考虑一下，这一切都是有道理的。_{不，实际上不是。^{实际上，它确实...}}

from random import *
commands = ""
while len(commands) < 3:
    chance = random()
    if chance < .5: commands += "V"
    elif chance < .66: commands += "I"
    elif chance < .84: commands += "E"
    else: commands += "M"

print(commands)

我是来帮忙的。

治愈

这似乎太简单了，但它似乎也是降低感染/死亡率的一种很好的方法。每转，输出MCQ：

• 降低感染率
• 治愈一些感染
• 隔离剩下的一些感染者

而已！

public class TheCure{
    public static void main(String[]a){
        System.out.println("MCQ");
    }
}

如果目前没有被感染的话，我可以通过输出更多M（或B）而不是进行固化和隔离来改善此效果，但我想先看看效果如何。不幸的是，先发布的一个副作用是很难评估有效性：

这个机器人可以生存直到所有讨厌的玩家都死了。在那之后，它治愈了人口，并为健康的人口重新安置了该镇。

该机器人有5个步骤：

1. 封闭边界。
2. 让被感染者死亡，但不要过快死亡（准确地确定过快的速度是困难的部分）。
3. 防止被感染者感染健康。
4. 治愈感染者（用盐：P）。
5. 复制。

PureBot（Haskell）

PureBot讨厌一件事：副作用！
它会尝试处理所有副作用，如果一切顺利，它将减少外界产生的副作用。
它也忽略了其计算中的所有副作用。
这使得它在对抗被动敌人（不会改变整体速度）方面表现更好。

如果infected，infection，contagion，lethality和migration都是零，这将有助于其他机器人与P（对Pure）命令。
