我必须为一所大学的 6 门课程制定时间表。以下是我想出的课程。

class ClassRoom  
{  
    private:  
    char id[5];
    char type;
    int cap;
public:
    void setRoom();
    void disp();
}c[15];
class StudentGroup
{
    int sem;
    char group[3];
    int strength;
  public:
    void setGroup();
}stud[8];
class Course
{
    char courseID[7];
    int semNo;
    char courseCode[5];
    char courseName[50];
    char type;
    int lec;
    int tut;
    int prac;
public:
    void setCourse();
}cour[75];
class CourseDetails
{
    public:
  char courseID[7];
  char preference[3];
  char resourceType;
  char classPref[3];
};
class Faculty
{
  char facID[6];
  char name[50];
  int noCourses;
  public:

  CourseDetails cD[6];
      void setFaculty();
      void disp();
}fac[50];
class ElecPair
{
    int noPaired;
    char courseId[10][7];
public:
    void setElecPair();
}ePair[10];
class Period
{
    int semNo;
    char className[3];
    char courseID;
    char facID;
    bool availability;
};
class TimeTable
{
    Period prd[5][7];
}tt[6];

我必须创建具有通常限制的时间表：
没有老师可以同时在 2 个班级。
没有学生可以同时上 2 个班级，依此类推。
我不想要代码，但我想获得有关在不使用遗传算法的情况下生成此时间表的最佳方法的建议。
PS：有没有办法我可以使用堆栈或递归来生成这个时间表？

我用 c# 写了一个简单的算法，可以解决在同一给定时间内教师、房间和讲座之间的 0 冲突的时间表问题。它的想法很简单： 1- 为每个老师生成可能的讲座（老师+时间段）。2 - 为每个房间（房间+时间段）生成可能的讲座。3- 从给定的teacher_periods 列表中随机抽取一个周期并检查两件事。a - 这个随机周期是否存在于房间周期中？b - 这个随机时间不是由同一班学生参加的吗？？如果这两个条件都成立，那么你必须做 3 件事： 1- 选择一个具有相同时期的房间并将其添加到解决方案中（在解决方案列表中）。2- 从教师时段和房间时段列表中删除这段时间。否则，重复该过程。公共类程序{

  static List<Room> rooms ;

    private static List<Room> GetListeOfRoomsFomSource()
    {
        throw new NotImplementedException();
    }

    public static  void Main(string[] args)
    {
        var listTeachers = GetListeOfTeachersFomSource();
        rooms= GetListeOfRoomsFomSource();
        foreach (var techer in listTeachers)
        {

            var temp = techer.periods.ToList();
            var rnd = new Random();
            var rnd2 = new Random();
            var period = 0;

            var exist = false;
            do
            {
                if (temp.Count == 0) break;
                int index = rnd.Next(0, temp.Count - 1);
                period = temp[index];
                exist = CheckIfLectureExist(period, section,techer);
                temp.Remove(temp[index]);

            } while (!exist);
            if (exist)
            {
                AddSolution( techer,period);
            }
            else
            {
                AddNoSolution();
                // list.Remove(tc1);
            }

        }




    }

    private static void AddSolution( Teacher item, int period)
    {
        // get a random room with the this given period;

        var lisOfrooms = new List<Room>();
        foreach (var room in rooms)
        {

        var availableRoom = lisOfrooms[r2];
        // create solution which is a combination of the techer + availableRoom + period  + class.
        //remove the period from the periods of the given techer;

        //remove the period from the periods of the given room;
        //r;
    }

    private static void AddNoSolution()
    {
        throw new NotImplementedException();
    }

   private static bool CheckIfLectureExist(int period, object classRoom ,Teacher teacher)
    {
       // chech if this period has an available (free) room in the list of rooms.
       // chech if this period + classroom + techer does not exist in the solutions to avoid the conflict between classes.
       throw new NotImplementedException();
    }

    private static  List<Teacher> GetListeOfTeachersFomSource()
    {
        throw new NotImplementedException();
    }

public class Teacher{
    public Teacher (int periodsWeek)
    {
      _periodWeek = periodsWeek;
      GeneratePerids();
    }
    int _periodWeek;

    public void GeneratePerids(){

        {
            //populate periods;
