Can you Split Test In AdCenter?

Does Adcenter optimize the best ads?

[webpublisher]

I understand each Order can have multiple ads but what I can't confirm is whether Adcenter automatically displays the best performing ads over time.

I guess what I'm trying to say is does Adcenter work in the same way as Adwords when it comes to split testing. Are we able to add say 4 permutations of an ad and watch Adcenter display the better ad over time.

Searched in the Help section but couldn't find anytime to confirm this.
