各位前輩們
以下是我程式問題
我使用方法與陣列去亂數隨機生成50棵樹根與左右子樹
我一步步除錯時，我的樹不會重複
但在程式自動執行的時候
樹會重複個幾次才會換新的之後又重複幾次(重複的次數沒有規律)
請問 是哪邊出了問題?
不好意思，剛學寫程式比較不會Debug
謝謝
以下是我的程式碼:
private void btn_createtree_Click(object sender, EventArgs e)
{
sp = float.Parse(num_select.Value.ToString()) / 100;
cp = float.Parse(num_crossover.Value.ToString()) / 100;
mp = float.Parse(num_mutation.Value.ToString()) / 100;
int rnd;
//generation = int.Parse(num_generation.Value.ToString());基因演化次數
population_size = int.Parse(num_population.Value.ToString());
string[,] tmptree = new string[population_size,3];//這一代幾棵樹
for (int i = 0; i < tmptree.GetLength(0); i++)
{
Random r = new Random();
rnd = r.Next(0, 5);
tmptree[i, 0] = operator_num[rnd].ToString();//root
level = r.Next(2, 6);//2到5層+1root
tmptree[i, 1] = create_tree(level);//left
level = r.Next(2, 6);
tmptree[i, 2] = create_tree(level);//right
show.Text += "No. " + (i + 1) + " tree：" + Environment.NewLine + "root：" + tmptree[i, 0] + Environment.NewLine + "left：" + tmptree[i, 1]
+ Environment.NewLine + "right：" + tmptree[i, 2] + " → level：" + level + Environment.NewLine + Environment.NewLine;
}
//fitness_sum = fitness_avg = 0;
}
private string create_tree(int level)
{
string s;
string[][] l = new string[level][];
Random r = new Random();
int rnd, count;
bool isfirst = true;
for (int i = 0; i < level; i++)
{
count = 0;
if (isfirst!=false)
{
isfirst = false;
rnd = r.Next(0, 5);//+-*/%隨機
l[i] = new string[] { operator_num[rnd].ToString() };
count += 2;
l[i + 1] = new string[count];
}
else if (i < level - 1 && i > 0)//第二至level-1層
{
for (int j = 0; j < l[i].Length; j++)
{
rnd = r.Next(0, operator_num.Length);
l[i][j] = operator_num[rnd].ToString();
if (rnd < 5)
count += 2;
else
count++;
}
l[i + 1] = new string[count];
}
else//最後一層開始
{
for (int j = 0; j < l[i].Length; j++)
{
rnd = r.Next(0, num_data);
l[i][j] = rnd.ToString();
}
}
}
//如何顯示
s = null;
for (int i = 0; i < l.GetLongLength(0); i++)
{
for (int j = 0; j < l[i].Length; j++)
{
if (j == l[i].Length - 1)
s += l[i][j] + " / ";
else
s += l[i][j] + ",";
}
}
return s;
}
一步步執行時結果(不會重複多筆)
