【解決方法】コーディングの課題: チェス盤の騎士

プログラミングQA


今日の課題は Jeroen Landheer によって提供されます。

騎士がチェス盤を飛び越えてすべてのマスに触れるようにするプログラムを作成しますが、その騎士は同じ場所を 2 回使用することはありません。 開始位置はユーザーが指定する必要があり (または、ユーザー入力を受け入れたくない場合はランダムな位置として指定する必要があります)、プログラムは解を計算して座標のリストに出力する必要があります。

例：

開始: A1
解決策: A1 – B3 – C5 など

先週

彼の多言語解決策に対する ProgramFOX への特別な言及。 素晴らしい。 優勝者は、ヨルゲン・アンダーソンとグレームの間で互角だったが、グレームにさらに高い狂気の偉業をもたらすことを期待して、私はヨルゲンにそれを与えるつもりだ.

解決策 1

Warnsdorff のアルゴリズムの解釈を使用した解決策を次に示します。 騎士のツアー – ウィキペディア[^]

アップデート： コードは、パフォーマンスを犠牲にすることなくリファクタリングされました。

目的

次の目標を持つ柔軟なコア:

1. 次のような他のボード指向のパズルで再利用します。 エイト クイーンズ パズル – ウィキペディア[^]、 ルーク多項式 – ウィキペディア[^]、 と ノースリーインライン問題 – ウィキペディア[^].

2. その他の「ボーナス」タスク:
2a. 特定のボード サイズで解けるすべてのツアーを決定する
2b. 有効な解決策で最小基板サイズを決定する
2c。 決闘の騎士 – ボード上に 1 人以上の騎士がいる解決可能な解決策。
2d。 ユーザーは、ツアーを前後に視覚的にナビゲートし、行われている動きだけでなく、意思決定プロセスがどのように機能するかを確認できます。
2e. パフォーマンス – パフォーマンスよりも柔軟性を犠牲にしない

上記の目的をすべて達成するために、私は Stack(T) クラス (System.Collections.Generic)[^].

コアコード

コードは、PCL (ポータブル クラス ライブラリ) に含まれています。

パフォーマンス目標を達成するために、 Knight クラスが初期化されると、ボードがリセットされ、すべてのポジションの動きが事前に計算されます。

1. Location クラス：

C#
public class Location // a Knight's move
{
    public Location(int cols, int rows, int index)
    {
        this.cols = cols;
        this.rows = rows;
        this.index = index;
    }

    public Location(int cols, int rows, int index, int moveNum)
        : this(cols, rows, index)
    {
        this.moveNum = moveNum;
    }

    int cols, rows, iRow, col, row, index, moveNum;

    public int MoveNum => moveNum;

    public int Index => index;

    public int Col
    {
        get
        {
            if (col == 0) calcCoords();
            return col;
        }
    }

    public int Row
    {
        get
        {
            if (row == 0) calcCoords();
            return row;
        }
    }

    private void calcCoords()
    {
        col = index % cols;
        row = index / cols;
        iRow = rows - row;
    }

    public override string ToString()
    {
        if (col == 0) calcCoords();
        if (col < 26) return $"{(char)(col % 26 + 'A')}-{iRow}";
        if (col < 52) return $"{new string('A', col / 26) + (char)(col % 26 + 'A')}-{iRow}";
        return $"{"AZ" + (col - 52).ToString()}-{iRow}";
    }
}

2. Board クラスとインターフェース:

C#
using System.Collections.Generic;

public interface IBoard
{
	int Columns { get; }
	List<List<int>> Locations { get; }
	IEnumerable<int> Missed { get; }
	int Rows { get; }
	IRule Rules { set; }
	bool[] Visited { get; }

	Location Init(int? cellId = default(int?));
	void ResetVisits();
	void UndoVisit(int index);
} 

public class Board : IBoard
{
    public Board(int columns, int rows)
    {
        Columns = columns;
        Rows = rows;
        Size = columns * rows;
    }

    public int Size { get; }

    public int Rows { get; } = 8;

    public int Columns { get; } = 8;

    public List<List<int>> Locations { get; private set; }
        = new List<List<int>>();

    public IEnumerable<int> Missed
        => Locations.Where((x, i) => !Visited[i]).Select((x, i) => i);

    private static bool[] visited;
    public bool[] Visited => visited;

    public IRule Rules { private get; set; }


    public Location Init(int? locationId = null)
    {
        totalLocations = Columns * Rows;
        BuildMovesTable();
        return new Location(Columns, Rows,
			locationId.HasValue && locationId.Value > -1 
				? locationId.Value : r.Next(0, totalLocations), 0);
    }

    public void ResetVisits()
    {
        visited = new bool[totalLocations];
    }

    public void UndoVisit(int index)
    {
        Visited[index] = false;
    }

    private int totalLocations;
    private Random r = new Random();

    private void BuildMovesTable()
    {
        ResetVisits();
        RebuildTable();
    }

    private void RebuildTable()
    {
        Locations = Enumerable.Range(0, totalLocations)
                                .Select(x => Rules.BuildLocation(x))
                                .ToList();
    }
}

3. Knight クラス ＆ IRule インターフェース：

C#
using System.Collections.Generic;

public interface IRule
{
	List<int> BuildLocation(int index);
} 

public class Knight : IRule
{
	public Knight(IBoard board, int? startLocation = null)
	{
		Board = board;
		board.Rules = this;
		Init(startLocation);
	}

	public void Init(int? startLocation)
	{
		Board.ResetVisits();
		Moves = new Stack<Location>();
		Moves.Push(Board.Init(startLocation));
		CanMoveNext = true;
	}

    public IBoard Board { get; }

    public Location Start => Moves?.Last();

    public Location Current => Moves?.Peek();

    public Stack<Location> Moves { get; private set; }

    public bool CanMoveNext { get; private set; }

    public void ExecuteMoves()
    {
        while (true) { if (MoveNext() == null) break; }
    }

    public Location MovePrevious()
    {
        if (Moves.Count > 0) Board.Visited[Moves.Pop().Index] = false;
        CanMoveNext = true;
        return Moves.Count > 0 ? Moves.Peek() : null;
    }

    public Location MoveNext()
    {
        var index = Moves.Peek().Index;
        var c1 = Board.Locations[index];
        int ndx = 0, score = int.MaxValue;

        for (int i = 0; i < c1.Count; i++)
            if (!Board.Visited[c1[i]] && c1[i] != index)
            {
                var tscore = 0;
                var c2 = Board.Locations[c1[i]];
                for (int j = 0; j < c2.Count; j++)
                    if (!Board.Visited[c2[j]] && c2[j] != i) tscore++;

                if (tscore < score)
                {
                    ndx = c1[i];
                    score = tscore;
                }
            }

        Board.Visited[index] = true;

        CanMoveNext = score != int.MaxValue;
        if (CanMoveNext)
        {
            var newLoc = new Location(Board.Columns, Board.Rows, ndx, Moves.Count);
            Moves.Push(newLoc);
            return newLoc;
        }
        return null;
    }

    List<int> IRule.BuildLocation(int index)
    {
        var loc = new List<int>();
        int pc = index % Board.Columns, pr = index / Board.Columns;
        for (int k = 0; k < rules.GetLength(0); k++)
        {
            int nc = pc + rules[k, 0], nr = pr + rules[k, 1];
            if (nc < Board.Columns && nc > -1 && nr < Board.Rows && nr > -1)
                loc.Add(nr * Board.Columns + nc);
        }
        return loc;
    }

    private readonly int[,] rules = new int[,]
    {
    { -1, -2 }, {  1, -2 }, {  2, -1 }, {  2,  1 },
    {  1,  2 }, { -1,  2 }, { -2,  1 }, { -2, -1 }
    };
}

ノート: 最初のツアーは 8 x 8 のチェス盤で、4 人の騎士がランダムに配置されます。 開始場所によっては、すべての 4 ナイト ツアーが完了するわけではない可能性があります。 ただし、このパズルが解ける可能性はあります。 実験して楽しんでください。

ボーナス タスク 4 – ナビゲーション付きレトロ ビジュアル ソルバー

このタスクは、タイトルが示すように非常に単純なものです – 前後に移動し、ボードが解決されるのを見てください。 これは、それだけではありません。 言葉で説明するよりも、写真の方がよくわかります… スクリーンショット[^]

このプロジェクトには数百行のコードがあるため、ここにすべてを掲載するのではなく、以下にダウンロード可能なリンクを用意しました。これを試して、騎士の動きだけでなく、アルゴリズムがどのように機能するかを視覚的に正確に確認できます。ボードのツアーで。 😉

これは、ユーザーが前後に移動できるようにするコア ナビゲーション コードの抜粋です。 ナビゲーションは、方向ごとに 1 行だけで、ツアーの最後にいるかどうかを確認します。

C#
private static void TourGuide(int cols, int rows)
{
    InitWorkArea(cols, rows);
    knight = new Knight(new Board(cols, rows));
    UpdateLocation(knight.Moves.Peek());

    bool Active = true;

    while (Active)
    {
        switch (Console.ReadKey(true).Key)
        {
            case ConsoleKey.P:

                isPreview = !isPreview; // show/hide
                break;

解決策 5

うーん、私の解決策は完全ではありません。 この問題は私にとってあまり興味深いものではありませんが、理論的には、徹底的なバックトラッキングの実装を持っています。 全て ツアー。 6×6 のボードを指定すると、約 1 時間で正方形 (0,0) からのすべてのツアーであることがわかりました。 しかし、チェス盤 (8×8) が与えられた場合、それは 2 日間実行されており、まだ結果は報告されていません。

現時点で言えることは、ボードの 2 次元表現ではなく、ノードのグラフ (ネットワーク) を使用するということだけです。 再帰もありません。

探すことに興味がない a ツアーや どれでも ツアー、私はクローズド ツアーを探しています。ネットから転記するのが面倒です。 自分で見つけたい。

からのクローズドナイツツアー どれでも スクエアはクローズドナイツツアーです 毎日 四角。

とにかく、チャレンジの解決策として、私の計画は次のとおりです。
与えられた（まあ、そうではない 与えられた、上記のように）チェス盤のクローズドナイトツアー…
ツアーをハードコードし、毎回使用するだけです。
開始場所として指定された広場が何であれ、そこからハードコードされたツアーを開始し、ツアーを行います。
終わり
（私はあなたに最新情報を提供しようとします。）

そうは言っても、グラフトラバースの実装があるので、グラフのトラバースに関するより一般的な質問に対処するためにコードを一般化することを検討しています。 実は、80年代中盤の、完全に解けなかったパズルがあって、ときどき（白鯨のように）思い浮かびますが、このテクニックを応用できるのではないかと思います。

更新: 1 つの仮想 CPU を 100% 使用して丸 1 週間実行した後、私のコードはツアーをまったく検出しませんでした。 それを殺して問題を見つける時が来ました…
