哈哈～初一也是要發文～

最近又跑出一個問題，說是上一篇中有提到因為雙方的策略一致，導致勝率是佔各半（沒有平手，因為沒有分數一樣的問題）。但是如果兩個人的策略不一樣的話會怎樣呢～
我們先設總共有100家店，我和敵人個從商店街的兩邊開始走，我用一種策略，他用一種策略，跑10,000次後，我方勝率會是多少...
100家的話就會有100x100=10,000種。要跑10,000次的話，要循環100,000,000次，真的這樣跑的話，四天跑不掉...所以我打算敵我方的策略只做50家就好，這樣時間就可以控制在一天就好...程式如下：

<?php

    for ($i=1;$i<count($argv);$i++)
    {
        $it = explode("=",$argv[$i]);
        $_GET[$it[0]] = $it[1];
    }

$n="\n";
$brn="<br />\n";

date_default_timezone_set("Asia/Taipei");

還有什麼變數呢...？
如果我很壞，只讓敵人告訴我他那一家的分數，但是我卻不告訴他呢？這樣的話一定是對我有利。對我有弊的話應該就是告訴他我這家的分數，但是她不告訴我吧...最慘的是，我不告訴她，他也不告訴我，這樣就是在沒有網路的世代會做的事...XD

程式如下：

我看得到對方，但是對方看不到我那一家的分數時的程式。其實就只是改一下判斷標準罷了...如下：
mode=5 I can see you, you can't see me...

   if($time>0 and $num>=$percent_num and $num>=$army_percent_num) {
    $choice=$choice+$num;
    $time=$time-1;
    $thisnum[$i]=0;
    }//拿走
    
    if($army_time>0 and $army_num>=$army_percent_num) {
    $army_choice=$army_choice+$army_num;
    $army_time=$army_time-1;
    $thisnum[$limit-$i-1]=0;
   }//敵方拿走

第三個是別人看得到我，但是我看不到別人的程式～
mode=5 I can't see you, you can see me...

   if($time>0 and $num>=$percent_num) {
    $choice=$choice+$num;
    $time=$time-1;
    $thisnum[$i]=0;
    }//拿走
    
    if($army_time>0 and $army_num>=$army_percent_num and $army_num>=$percent_num) {
    $army_choice=$army_choice+$army_num;
    $army_time=$army_time-1;
    $thisnum[$limit-$i-1]=0;
   }//敵方拿走

最後一個是我們兩個各自看不到對方的程式～
mode=5 I can't see you, you can't see me too...

   if($time>0 and $num>=$percent_num) {
    $choice=$choice+$num;
    $time=$time-1;
    $thisnum[$i]=0;
    }//拿走
    
    if($army_time>0 and $army_num>=$army_percent_num) {
    $army_choice=$army_choice+$army_num;
    $army_time=$army_time-1;
    $thisnum[$limit-$i-1]=0;
   }//敵方拿走

明天看結果吧～
