void	SetSolverSpecificParameters (String parameters)
bool	SolverIsSupported ()
	Returns whether solver specified during the ctor was found and correctly installed.
bool	InterruptSolve ()
	Tries to interrupt the solve. Returns true if the feature is supported.

	Returns true if solve() was called, and a response was returned.
bool	HasSolution ()
	Returns true if solve() was called, and a solution was returned.
double	Value (Variable var)
	The value of a variable in the current solution. This raises a SolverException if no solution has been found, or if Solve() has not been called.
double	ReducedCost (Variable var)
	The reduced cost of a variable in the current solution. This raises a SolverException if no solution has been found, or if Solve() has not been called.
double	DualValue (LinearConstraint ct)
	The dual value of a linear constraint in the current solution. This raises a SolverException if no solution has been found, or if Solve() has not been called.
double	Activity (LinearConstraint ct)
	The activity of a constraint in the current solution. This raises a SolverException if no solution has been found, or if Solve() has not been called.

Properties
double	ObjectiveValue `[get]`
	The best objective value found during search. This raises a SolverException if no solution has been found, or if Solve() has not been called.
double	BestObjectiveBound `[get]`
	The best objective bound found during search. This raises a SolverException if no solution has been found, or if Solve() has not been called.
MbLogCallback	LogCallback `[get, set]`
	Sets the log callback for the solver.
double	WallTime `[get]`
	Returns the elapsed time since the creation of the solver.
double	UserTime `[get]`

Parameters

solverName the name of the solver backend

Definition at line 41 of file ModelSolver.cs.

Member Function Documentation

◆ Activity()

double Google.OrTools.ModelBuilder.Solver.Activity ( LinearConstraint ct )

inline

Definition at line 187 of file ModelSolver.cs.

◆ EnableOutput()

void Google.OrTools.ModelBuilder.Solver.EnableOutput ( bool enable )

inline

Enables or disables the underlying solver output.

Parameters

enable the Boolean that controls the output

Definition at line 74 of file ModelSolver.cs.

◆ HasResponse()

bool Google.OrTools.ModelBuilder.Solver.HasResponse ( )

inline

Returns true if solve() was called, and a response was returned.

Returns: whether solve did happen

Definition at line 113 of file ModelSolver.cs.

◆ HasSolution()

bool Google.OrTools.ModelBuilder.Solver.HasSolution ( )

inline

Returns true if solve() was called, and a solution was returned.

Returns: whether a solution was found

Definition at line 122 of file ModelSolver.cs.

◆ InterruptSolve()

bool Google.OrTools.ModelBuilder.Solver.InterruptSolve ( )

inline

Tries to interrupt the solve. Returns true if the feature is supported.

Returns: whether the solver supports interruption

Definition at line 104 of file ModelSolver.cs.

◆ ReducedCost()

double Google.OrTools.ModelBuilder.Solver.ReducedCost ( Variable var )

inline

The reduced cost of a variable in the current solution. This raises a SolverException if no solution has been found, or if Solve() has not been called.

Definition at line 174 of file ModelSolver.cs.

◆ SetSolverSpecificParameters()

void Google.OrTools.ModelBuilder.Solver.SetSolverSpecificParameters ( String parameters )

inline

Sets solver specific parameters as string.

Definition at line 86 of file ModelSolver.cs.

◆ SetTimeLimitInSeconds()

void Google.OrTools.ModelBuilder.Solver.SetTimeLimitInSeconds ( double limit )

inline

Sets the time limit for the solve in seconds.

Definition at line 80 of file ModelSolver.cs.

◆ Solve()

SolveStatus Google.OrTools.ModelBuilder.Solver.Solve ( Model model )

inline

Solves given model, and returns the status of the response.

Parameters

model the model to solve

Returns: the status of the solve

Definition at line 52 of file ModelSolver.cs.

◆ SolverIsSupported()

bool Google.OrTools.ModelBuilder.Solver.SolverIsSupported ( )

inline

Returns whether solver specified during the ctor was found and correctly installed.

Returns: whether the solver is supported or not

Definition at line 95 of file ModelSolver.cs.

◆ Value()

double Google.OrTools.ModelBuilder.Solver.Value ( Variable var )

inline

The value of a variable in the current solution. This raises a SolverException if no solution has been found, or if Solve() has not been called.
