Since most trees hosted on the internet, including on Ancestry.com, are mostly junk, it matters not how logical an algorithm is constructed to stitch a bunch together. No computer algorithm can evaluate whether items attached to individuals or families were applicable, or whether any evidence was the basis of X assertion as to event time/place or relationships. Myriad tree owners don't even get place-names spelled right (oh, so many are just copied from copies of copies . . . .).
