画像をスキャンして宝石を特定の数値に変換するプログラムがあります。下の図を見てください。
だから私は数字の表を持っています。数字の 1 は黄色の宝石、2 は青など...
お気に入り：
A B C D E
1 | 1 2 3 4 5
2 | 3 5 2 4 1
3 | 1 4 4 1 2
4 | 3 3 2 1 5
5 | 5 1 5 2 5
水平または垂直に 3 つの等しい数 (宝石) を取得するために、ステップを計算したいと考えています。たとえば、この表で、E2 を D2 と交換すると、D2 は 1 になり、D2、D3、D4 はすべて 1 であるため、有効なステップを作成します。私は VB.NET 2010 を使用しています。
私のテーブルは 8x8 サイズです。これは上の例にすぎません。
今、私は複数の変数に値を持っているだけです（A1 = 1、A2 = 3など..）
私の質問を理解していただければ幸いです。
どうぞ：

このプログラムは、任意のボード サイズで動作します。このプログラムは、私がゲーム内で一致を検索する方法に基づいています (これは力ずくだと思います)。
編集
ソルバーは最初の gem で一致を見つけることができなかったようです (以下のサンプルを参照)。
5、2、5 2、5、3 1、5、4
上記のサンプルにアルゴリズムが適用された場合、一致するものは見つかりません。
私は今それを修正しました。IsMatchOnFirst()これらのケースを処理するメソッドが用意されました。
変更については、更新されたコードを参照してください。
