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)
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data algorithm" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (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 tree algorithms") OR ("element update algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data routing algorithm\") OR (((\"element tree algorithms\") OR (\"element update algorithm\"))))".
• Removing quotes may allow a broader search: (( data routing algorithm ) OR ((( element tree algorithms ) OR ( element update algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data routing algorithm") OR ((("element tree algorithms") OR ("element update algorithm"))))*.
