[英]How to deal with an active model already present in Microsoft Solver Foundation?
I used the library to solve line equation, it works for one creation of a class object from this library, but when I want to re-create the object, it throws me away: 我使用库来解决线方程,它适用于从这个库创建一个类对象,但是当我想重新创建对象时,它会抛弃我:
System.InvalidOperationException: There is already an active model in the context. System.InvalidOperationException:上下文中已存在活动模型。 At
Microsoft.SolverFoundation.Services.SolverContext.CreateModel ()
在Microsoft.SolverFoundation.Services.SolverContext.CreateModel ()
The problem is that after counting the first example, I want to change data and click on the button and get results for another example. 问题是,在计算第一个例子之后,我想要更改数据并单击按钮并获得另一个示例的结果。
class LinearResolve
{
public string[] Zmienne = new string[3];
public LinearResolve(string[] table)
{
Zmienne = table;
}
public string Solver()
{
SolverContext context = SolverContext.GetContext();
Model model = context.CreateModel();
Decision a = new Decision(Domain.Real, "a");
Decision b = new Decision(Domain.Real, "b");
Decision c = new Decision(Domain.Real, "c");
model.AddDecisions(a, b, c);
model.AddConstraint("eqA", Zmienne[0]);
model.AddConstraint("eqB", Zmienne[1]);
model.AddConstraint("eqC", Zmienne[2]);
Solution solution = context.Solve();
string results = solution.GetReport().ToString();
return results;
}
}}
Call ClearModel
first: 首先调用ClearModel
:
SolverContext context = SolverContext.GetContext();
context.ClearModel();
Model model = context.CreateModel();
