这个问题的解为：
Global optimal solution found.
Objective value: 162400.0
Infeasibilities: 0.000000
Total solver iterations: 2
Model Class: LP
Total variables: 3
Nonlinear variables: 0
Integer variables: 0
Total constraints: 4
Nonlinear constraints: 0
Total nonzeros: 12
Nonlinear nonzeros: 0
Variable Value Reduced Cost
X1 94.00000 0.000000
X2 218.0000 0.000000
X3 0.000000 0.000000
Row Slack or Surplus Dual Price
1 162400.0 1.000000
2 0.000000 100.0000
3 62.40000 0.000000
4 0.000000 200.0000
这是全局最优解,也就是说不存在多个解的情况.
