I have noticed Yahoo is switching ranking algorithems. Also it is clear for me that Yahoo search results are changing with alogorithem changes.

I would not say they are switching their algo more like fine turning it!

I 've noticed that they have filtered results where "store.yahoo" results were showing affiliate resultes to the base Yahoo store result.

Their algo is most likely based on an old Google algo before yahoo anounced their own SE. I would guess it's based on a Google algo about 9 months old.

You could be right. One more thing. Yahoo uses two different alogorithems in Yahoo.com and Yahoo.co.uk?
