配牌を取った時のシャンテン数(通常手のみ)の割合をシミュレートします。いままで作ったプログラムを使って結果がどんな感じになるかを見てみましょう。
プログラムの解説と実行
前回のお題の配牌のシャンテン数をシミュレートするに続き、配牌を取ったあとの最初のツモでシャンテン数の割合がどのくらいになるかをシュミレートしてみます。手順は同じです。親がサイコロを振って配牌を取り出すイメージです。13牌で配牌が完了。違いはさらに1牌ツモって手牌が14牌になるだけです。
実行方法と試行回数に要する時間
[開始]ボタンで作業をスタートします。試行回数は1000回です。[中断]ボタンで作業を途中で終わらせることができます。試行回数はプログラム中のグローバル変数の初期値を書きかえれば変更できます。
var numTrials = 1000;//試行回数:この値を変えることで試行回数を調整できます

作業が終わったら[結果を出力]ボタンで集計結果を確認できます。
シャンテン数の割合を算出した結果は、あくまでシミュレートによるものです。本プログラムで導かれた数値は、実際のリアル麻雀やネット麻雀で一致するとは限りません。参考程度にとどめておいてください。
親の配牌:試行回数 = 0
シャンテン数:「0」はテンパイ、「-1」はアガリになります。
