# LogControl

### GetStateLogPeriod

```csharp
public override int GetStateLogPeriod()
```

#### 정의

State 로그를 기록하는 주기를 설정합니다. 예를 들어, 5000으로 설정되었을 경우 5000개의 State 마다 한번씩 로그를 기록합니다.

#### 예제 (Default Logic)

```csharp
public override int GetStateLogPeriod()
{
    return 5000;
}
```

### WriteSolution

```csharp
public override void WriteSolution(Solution solution)
```

#### 정의

Solution을 기록합니다.

#### 예제

```csharp
public override void WriteSolution(Solution solution)
{
    StringBuilder jobStr = new StringBuilder();
    StringBuilder colorStr = new StringBuilder();
    StringBuilder convStr = new StringBuilder();

    IOrderedEnumerable<KeyValuePair<int, State>> states = solution.States.OrderBy(x => x.Key);

    foreach (KeyValuePair<int, State> item in states)
    {
        CRPState state = item.Value as CRPState;

        if (state.IsInitial)
            continue;

        jobStr.Append(state.LastRetrievedJob.Number);
        colorStr.Append(state.LastRetrievedJob.Color.ColorNumber);
        convStr.Append(state.CurrentConveyor.ConveyorNum);

        if (state.JobCount > 0)
        {
            jobStr.Append("-");
            colorStr.Append("-");
            convStr.Append("-");
        }
    }

    Console.WriteLine(string.Format("Job Sequence: {0}", jobStr.ToString()));
    Console.WriteLine(string.Format("Color Sequence: {0}", colorStr.ToString()));
    Console.WriteLine(string.Format("Conveyor Sequence: {0}", convStr.ToString()));
}
```

### IsExportStateLog

```csharp
 public override bool IsExportStateLog()
```

#### 정의

State 로그를 파일로 Export 할지 여부를 설정합니다.

#### 반환

<table><thead><tr><th width="169.33333333333331">Type</th><th width="348">Description</th><th>Default</th></tr></thead><tbody><tr><td>Boolean</td><td>State 로그 Export 여부입니다.</td><td>False</td></tr></tbody></table>

#### 예제

```csharp
public override bool IsExportStateLog() 
{
    return false;
}
```

### WriteBestSolutionLog

```csharp
public override void WriteBestSolutionLog()
```

#### 정의

현재까지의 Best Solution에 대한 로그를 기록합니다.

#### 예제

```csharp
public override void WriteBestSolutionLog()
{
    SolutionManager solutionManager = SolutionManager.Instance;
    Solution bestSol = solutionManager.BestSolution;

    Console.WriteLine(Constants.LINE);
    Console.WriteLine(string.Format("Objective Value: {0}", bestSol.Value));
    this.WriteSolution(bestSol);
    Console.WriteLine(Constants.LINE);
}
```

### WriteOptimalLog

```csharp
public override void WriteOptimalLog()
```

#### 정의

최적해를 찾고 난 후 로그를 기록합니다.

#### 예제

```csharp
public override void WriteOptimalLog()
{
    SolutionManager solutionManager = SolutionManager.Instance;
    Solution optSol = solutionManager.OptimalSolution;

    Console.WriteLine(Constants.LINE);
    Console.WriteLine(string.Format("Optimal Objective Value: {0}", optSol.Value));
    this.WriteSolution(optSol);
    Console.WriteLine(Constants.LINE);
}
```

### WritePruneLog

```csharp
public override void WritePruneLog(State state)
```

#### 정의

State가 Prune 되었을 때 로그를 기록합니다.

#### 예제

```csharp
public override void WritePruneLog(State state)
{
    Console.WriteLine("Prune => StateIndex:{0}, State:{1}, Stage:{2}, DualBound:{3}, BestValue:{4}, BestPrimalBound:{5}", state.Index, state.ToString(), state.Stage.Index, state.DualBound, state.BestValue, BoundManager.Instance.BestPrimalBound);
}
```

{% hint style="info" %}
State가 Prune 되는 경우가 많을 수 있기 때문에 특별한 사유가 없으면 로그를 기록하지 않는 것을 권장합니다.
{% endhint %}
