Perhaps you should try some spelling variations:
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "image processing 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)
"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)

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 processing algorithm") OR ((("develop tree algorithms") OR ("element update algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"develop tree algorithms\") OR (\"element update algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( develop tree algorithms ) OR ( element update algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("develop tree algorithms") OR ("element update algorithm"))))*.
