我正在做一个简单的求解器练习,我正在努力使用Math.Pow
.
为什么我不能Math.Pow(error1, 2)
在以下几行中使用?
error1 = error1 * error1;
error2 = error2 * error2;
它给出了一个错误:
错误 3 参数 1:无法从“Microsoft.SolverFoundation.Services.Term”转换为“double”
相关代码:
using Microsoft.SolverFoundation.Common;
using Microsoft.SolverFoundation.Services;
...
private void Form1_Load(object sender, EventArgs e)
{
var solver = SolverContext.GetContext();
var model = solver.CreateModel();
Decision R = new Decision(Domain.Real, "R");
Decision T = new Decision(Domain.Real, "T");
model.AddDecisions(R);
model.AddDecisions(T);
var xr1=5;
var xr2=4;
var xp1 = 6;
var xp2=8;
var error1 = xr1 * R + T - xp1;
var error2 = xr2 * R + T - xp2;
error1 = error1 * error1;
error2 = error2 * error2;
model.AddGoal("error",GoalKind.Minimize,error1+error2);
var solution = solver.Solve();
var valordeR = R.GetDouble();
var valordeT = T.GetDouble();
}
