 # BoundsMustBeSpecifiedException class

 Last update: 19.06.2026 

**Namespace:** `Phoenix.Optimization`

## Overview

This can be thrown from the algorithm when the algorithm is passed a problem definition that has an open bound upper or lower bound on the constraints or design variables and the algorithm does not support open bounds.

### BoundsMustBeSpecifiedException()

```csharp
BoundsMustBeSpecifiedException ( )

```

Initializes a new instance of the `BoundsMustBeSpecifiedException` class.

### BoundsMustBeSpecifiedException()

```csharp
BoundsMustBeSpecifiedException ( string msg)

```

Initializes a new instance of the `BoundsMustBeSpecifiedException` class with a specified error message.

**Parameters:**

- `msg` - Message for the exception

### BoundsMustBeSpecifiedException()

```csharp
BoundsMustBeSpecifiedException ( string algorithm, string variables )

```

Initializes a new instance of the `BoundsMustBeSpecifiedException` class specifing the algorithm throwing the error and the variables that require bounds.

**Parameters:**

- `algorithm` - Name of algorithm throwing exception.
- `variables` - Names of variables that require bounds.

### BoundsMustBeSpecifiedException()

```csharp
BoundsMustBeSpecifiedException ( string msg, Exception inner )

```

Initializes a new instance of the `BoundsMustBeSpecifiedException` class with a specified error message and a reference to the inner exception that is the cause of this exception.

**Parameters:**

- `msg` - The error message that explains the reason for the exception.
- `inner` - The exception that is the cause of the current exception, or a null reference (`Nothing` in Visual Basic) if no inner exception is specified.

### BoundsMustBeSpecifiedException()

```csharp
BoundsMustBeSpecifiedException ( `SerializationInfo` info, `StreamingContext` context )

```

Initializes a new instance of the `BoundsMustBeSpecifiedException` class with serialized data.

**Parameters:**

- `info` - The `SerializationInfo` that holds the serialized object data about the exception being thrown.
- `context` - The `StreamingContext` that contains contextual information about the source or destination.
