Can anyone help me solve this problem？

Hi, I am a CS master in TYUST, I'm very interested in Disout.
But I could not find this object function in your code

Can you tell me where it is in the code?
Think you !

Thanks for your interest. The simplified gradient of this objection function is used, which is discussed in Section 'Optimization of the Distortion'.
