# Configuration and command-line options |

|

*Work in progress!* |
||||
|
||||
|
||||
## Config-file and CLI options |
||||
|
||||
### algorithm |
||||
|
||||
Allows choosing between the few mining algorithms for incompatible |
||||
cryptocurrencies. |
||||
|
||||
*Argument:* string |
||||
|
||||
*Default:* `default` |
||||
|
||||
*Supported:* |
||||
|
||||
* `adaptive-nfactor` - Vertcoin-style adaptive N-factor scrypt. |
||||
N-factor defaults to 11. |
||||
* everything else - Litecoin-style static N-factor scrypt. |
||||
|
||||
|
||||
### nfactor |
||||
|
||||
Overrides the default scrypt parameter N, specified as the factor of 2 |
||||
(`N = 2^nfactor`). |
||||
|
||||
*Argument:* whole number (>1). |
||||
|
||||
*Default:* depends on `algorithm`; otherwise `10`. |
||||
|
||||
|
||||
## CLI-only options |
