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)
"elements tree algorithms" » "elements three algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res algorithms" (Expand Search)
"element each algorithm" » "element search algorithm" (Expand Search), "element means algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 processing algorithm") OR ((("elements tree algorithms") OR ("element each algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"elements tree algorithms\") OR (\"element each algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( elements tree algorithms ) OR ( element each algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("elements tree algorithms") OR ("element each algorithm"))))*.
