Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh algorithm" (Expand Search)
"relevant all algorithms" » "relevant _ algorithms" (Expand Search), "relevent le 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 ((("element mesh algorithm") OR ("relevant all algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element mesh algorithm\") OR (\"relevant all algorithms\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element mesh algorithm ) OR ( relevant all algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element mesh algorithm") OR ("relevant all algorithms"))))*.
