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 over algorithms" » "elements other algorithms" (Expand Search), "elements four algorithms" (Expand Search), "elements novel algorithm" (Expand Search), "elements under algorithms" (Expand Search), "elements mges algorithms" (Expand Search), "events over algorithms" (Expand Search)
"element forest algorithm" » "element ore 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 ((("element forest algorithm") OR ("elements over algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element forest algorithm\") OR (\"elements over algorithms\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element forest algorithm ) OR ( elements over algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element forest algorithm") OR ("elements over algorithms"))))*.
