### ModelEvaluation()

```csharp
ModelEvaluation ( )

```

Constructor Constructs a failed model evaluation. This constructor primarily exists to allow ModelEvaluation to be serialized.

### ModelEvaluation()

```csharp
ModelEvaluation ( double[] objectiveValues)

```

Constructor Assumes that there are no constraints. If objectiveValues is not null then the Run is assumed to not be failed, otherwise the Run is assumed to be failed.

**Parameters:**

- `objectiveValues` - double array of objective values

### ModelEvaluation()

```csharp
ModelEvaluation ( double[] objectiveValues, bool runFailure )

```

Constructor Assumes that there are no constraints. If objectiveValues is not null, then the runFailure value is used, otherwise the Run is assumed to be failed.

**Parameters:**

- `objectiveValues` - double array of objective values
- `runFailure` - boolean Run failure value

### ModelEvaluation()

```csharp
ModelEvaluation ( double[] objectiveValues, double[] constraintValues, bool runFailure )

```

Constructor If objectiveValues is not null, then the runFailure value is used, otherwise the Run is assumed to be failed.

**Parameters:**

- `objectiveValues` - double array of objective values
- `constraintValues` - double array of constraint values
- `runFailure` - boolean Run failure value

### ModelEvaluation()

```csharp
ModelEvaluation ( ModelEvaluation eval)

```

Copy constructor

**Parameters:**

- `eval` - ModelEvaluation to be copied

## Member Function Documentation

### ConstraintValues

```csharp
double [] ConstraintValues

```

Double array containing the values of the constraints.

### ObjectiveValues

```csharp
double [] ObjectiveValues

```

Double array containing the values of the objectives

### RunFailure

```csharp
bool RunFailure

```

Boolean contain stating whether the model evaluation was successful. The value will be true if there was an error evaluating the model, and false otherwise.

## Property Documentation

### ConstraintValues

```csharp
double [] ConstraintValues

```

Double array containing the values of the constraints.

### ObjectiveValues

```csharp
double [] ObjectiveValues

```

Double array containing the values of the objectives

### RunFailure

```csharp
bool RunFailure

```

Boolean contain stating whether the model evaluation was successful. The value will be true if there was an error evaluating the model, and false otherwise.
