线性规划问题:
max=3x1+2x2
x1+2x2<=5
2x1+x2<=4
4x1+3x2<=9
x1>=0
x2>=0
正确的结果:x1=1.5; x2=1, max z=6.5文章来源：https://www.toymoban.com/news/detail-646621.html
Random random1 = new Random(DateTime.Now.Millisecond);
Random random2 = new Random(DateTime.Now.Millisecond*DateTime.Now.Millisecond);
double max=-9999,x1=0,x2=0,resultX1=0,resultX2=0;
for (int i = 0; i < 654321; i++)
{
if (random1.Next(0, 100) % 2 == 0)
{
x1 = resultX1 + random1.NextDouble();
}
else
{
x1 = resultX1 - random1.NextDouble();
}
if (random2.Next(0, 100) % 2 == 0)
{
x2 = resultX2 + random2.NextDouble();
}
else
{
x2 = resultX2 - random2.NextDouble();
}
if (x1 + 2 * x2 <= 5 && 2 * x1 + x2 <= 4 && 4 * x1 + 3 * x2 <= 9)
{
if (3 * x1 + 2 * x2>max)
{
resultX1 = x1;
resultX2 = x2;
max = 3 * x1 + 2 * x2;
}
}
}
textBox1.Text = resultX1.ToString();
textBox2.Text = resultX2.ToString();
textBox3.Text = max.ToString();
