arguments :: [ArgCompletion]Source
The list of arguments supported by the program.
type Annotator = OpCode -> MetaOpCodeSource
Arguments
| :: Bool | Whether to print moves |
| -> Table | The starting table |
| -> Int | Remaining length |
| -> Bool | Allow disk moves |
| -> Bool | Allow instance moves |
| -> Bool | Resrict migration |
| -> Int | Max node name len |
| -> Int | Max instance name len |
| -> [MoveJob] | Current command list |
| -> Score | Score at which to stop |
| -> Score | Min gain limit |
| -> Score | Min score gain |
| -> Bool | Enable evacuation mode |
| -> IO (Table, [MoveJob]) | The resulting table and commands |
Start computing the solution at the given depth and recurse until we find a valid solution or we exceed the maximum depth.
