How to apply optimizers?

[c99]

Hi, everyone

I've got a message from cudaHashcat about optimizers available, but how do I enable them?
Couldn't figure out from help and forum.

The message was:

Applicable Optimizers:
* Zero-Byte
* Not-Iterated
* Single-Hash
* Single-Salt

If they are mentioned here, they are used for the current attack, you don't have to do any specific thing.

Good Lord, I thought it would read "Optimizers Applied" then.

Many thanks for disambiguation :-) , I'd never figure it out myself!
