Perhaps you should try some spelling variations:
"data routing algorithm" » "data modeling algorithm" (Expand Search), "data finding algorithm" (Expand Search), "data making algorithm" (Expand Search), "data groupings algorithm" (Expand Search), "data relating algorithm" (Expand Search), "data using algorithm" (Expand Search)
"elements two algorithms" » "elements ml algorithms" (Expand Search), "elements _ algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements wt algorithms" (Expand Search), "elements upon algorithms" (Expand Search)
"element based algorithm" » "engagement based algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("data routing algorithm") OR ((("element based algorithm") OR ("elements two algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data routing algorithm\") OR (((\"element based algorithm\") OR (\"elements two algorithms\"))))".
• Removing quotes may allow a broader search: (( data routing algorithm ) OR ((( element based algorithm ) OR ( elements two algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data routing algorithm") OR ((("element based algorithm") OR ("elements two algorithms"))))*.
