c# 木工二维优化下料算法代码

以下是一个简单的 C# 二维优化下料算法的代码示例：

using System;
using System.Collections.Generic;

namespace WoodCutting
{
    class Program
    {
        static void Main(string[] args)
        {
            List<WoodPiece> woodPieces = new List<WoodPiece>();
            woodPieces.Add(new WoodPiece(4, 8));
            woodPieces.Add(new WoodPiece(5, 7));
            woodPieces.Add(new WoodPiece(6, 6));
            woodPieces.Add(new WoodPiece(8, 4));
            woodPieces.Add(new WoodPiece(10, 3));

            List<WoodCut> woodCuts = OptimizeWoodCutting(woodPieces, 10, 20);

            Console.WriteLine("Optimized Wood Cuts:");
            foreach (WoodCut cut in woodCuts)
            {
                Console.WriteLine("Wood Piece: {0}x{1}", cut.Width, cut.Height);
                Console.WriteLine("Cut Location: ({0}, {1})", cut.X, cut.Y);
            }
        }

        static List<WoodCut> OptimizeWoodCutting(List<WoodPiece> woodPieces, int boardWidth, int boardHeight)
        {
            List<WoodCut> woodCuts = new List<WoodCut>();
            int x = 0;
            int y = 0;

            foreach (WoodPiece piece in woodPieces)
            {
                if (x + piece.Width <= boardWidth && y + piece.Height <= boardHeight)
                {
                    woodCuts.Add(new WoodCut(piece.Width, piece.Height, x, y));
                    x += piece.Width;
                }
                else
                {
                    x = 0;
                    y += piece.Height;
                    if (y > boardHeight)
                    {
                        throw new Exception("Board is not big enough to fit all wood pieces.");
                    }
                    woodCuts.Add(new WoodCut(piece.Width, piece.Height, x, y));
                    x += piece.Width;
                }
            }

            return woodCuts;
        }
    }

    class WoodPiece
    {
        public int Width { get; set; }
        public int Height { get; set; }

        public WoodPiece(int width, int height)
        {
            Width = width;
            Height = height;
        }
    }

    class WoodCut
    {
        public int Width { get; set; }
        public int Height { get; set; }
        public int X { get; set; }
        public int Y { get; set; }

        public WoodCut(int width, int height, int x, int y)
        {
            Width = width;
            Height = height;
            X = x;
            Y = y;
        }
    }
}

在这个例子中，我们有一个 `WoodPiece` 类来表示木材，一个 `WoodCut` 类来表示切割的木材块，以及一个名为 `OptimizeWoodCutting` 的函数来执行切割操作。在这个函数中，我们将每个木材块与木板的尺寸进行比较，并将其放置在可用空间内。如果木材块的宽度大于木板的宽度，则将其放置在下一行的开头。

请注意，此代码示例仅适用于基本的二维优化下料算法。实际应用中，您可能需要考虑更多因素，例如木材的形状和大小、切割顺序以及更高级的算法。
