SyntaxThe LinearConstrainedProblem type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | LinearConstrainedProblem | Constructs a LinearConstrainedProblem with no constraints. |
| LinearConstrainedProblem(LinearConstrainedProblem) | Copy constructor. |
Properties| Name | Description | |
|---|---|---|
 | Constraints | Gets and sets the linear constraints for the problem. |
| NumVariables |
Gets the number of variables in the problem.
(Inherited from BoundedVariableProblem) |
| VariableBounds |
Gets and sets variable bounds for the problem.
(Inherited from BoundedVariableProblem) |
Methods| Name | Description | |
|---|---|---|
| AddBounds(Int32, Double, Double) |
Adds upper and lower bound constraints to a variable.
(Inherited from BoundedVariableProblem) |

| AddEqualityConstraint(ILinearConstraintCoefficients, Double) | Adds an equality constraint of the form coefficients'x = rightHandSide |
| AddLowerBound(Int32, Double) |
Adds an lower bound constraint on the variable at the given index.
(Inherited from BoundedVariableProblem) |
| AddLowerBound(Int32, Double, Double) |
Adds an lower bound constraint on the variable at the given index.
(Inherited from BoundedVariableProblem) |
| AddLowerBoundConstraint(DoubleVector, Double) | Adds a linear inequality constraint of the form coefficients'x >= lowerBound |
| AddLowerBoundConstraint(ILinearConstraintCoefficients, Double) | Adds a linear inequality constraint of the form coefficients'x >= lowerBound |
| AddLowerBoundConstraint(DoubleVector, Double, Double) | Adds a linear inequality constraint of the form coefficients'x >= lowerBound |
| AddLowerBoundConstraint(ILinearConstraintCoefficients, Double, Double) | Adds a linear inequality constraint of the form coefficients'x >= lowerBound |
| AddUpperBound(Int32, Double) |
Adds an upper bound constraint on the variable at the given index.
(Inherited from BoundedVariableProblem) |
| AddUpperBound(Int32, Double, Double) |
Adds an upper bound constraint on the variable at the given index.
(Inherited from BoundedVariableProblem) |
| AddUpperBoundConstraint(DoubleVector, Double) | Adds a linear inequality constraint of the form coefficients'x <= upperBound |
| AddUpperBoundConstraint(ILinearConstraintCoefficients, Double) | Adds a linear inequality constraint of the form coefficients'x <= upperBound |

 | CheckVariableIndex |
Checks that the given variable index is valid.
(Inherited from BoundedVariableProblem) |
| EvaluateConstraints | Evaluates each of the constraints at the specified point and returns the results. |
| PointIsFeasible(DoubleVector) |
Function for determining the feasibility of a give point. A point
x is feasible if it satisfies all the constraints of the
problem.
(Overrides BoundedVariableProblemPointIsFeasible(DoubleVector)) |
| PointIsFeasible(DoubleVector, Double) |
Function for determining the feasibility of a give point.
