Perhaps you should try some spelling variations:
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data algorithm" (Expand Search)
"develop tree algorithms" » "develop three algorithms" (Expand Search), "develop art algorithms" (Expand Search), "develop two algorithms" (Expand Search), "develop new algorithms" (Expand Search), "develop targeted algorithms" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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: (((("develop tree algorithms") OR ("element update algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop tree algorithms\") OR (\"element update algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( develop tree algorithms ) OR ( element update algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop tree algorithms") OR ("element update algorithm"))) OR ("data using algorithm"))*.
