The Gulden developers have managed to create a truly CPU based mining algorithm like was intended for bitcoin. A couple developers I know who are avid miners weren't able to get Graphic cards running cost effectively against SIGMA.
For a coin that's not top 400 in marketcap I have to give them credit for this development.
That's true and it looks like you should add a reference about that like this one

I hope that more coin can follow this step as CPU may have the same chance as GPU too.
But it looks like SIGMA is pegged with argon as its main key to make GPU will less effective to mine.
