**Properties**

| Name | Type | Default | Description |
| --- | --- | --- | --- |
| `algorithm` | `string` |  | The algorithm that actually ran. |
| `seed` | `number` |  | The seed used — so a pleasing random layout can be reproduced on demand. |
| `selection?` | `LayoutSelectionReport` |  | . Present when the AUTO layout ran: which algorithm it chose, why, and what every other candidate scored. An auto-selector that cannot show its working is a support ticket. |
| `partial` | `boolean` |  | True when the run was cut short (cancelled, or out of time budget) and this is the BEST-SO-FAR answer rather than a finished one. |
| `reason?` | `LayoutStopReason` |  | Why it stopped early, when it did. |
| `iteration` | `number` |  | Iterations actually completed. |
| `totalIterations` | `number` |  | Iterations the algorithm would have run, left alone. |
