Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"based method algorithm" » "based mould algorithm" (Expand Search)
"element could algorithm" » "element mould algorithm" (Expand Search), "element carlo algorithm" (Expand Search), "element colony algorithm" (Expand Search), "elements could 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 ("based method algorithm"))) OR ("element could algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"based method algorithm\"))) OR (\"element could algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( based method algorithm ))) OR ( element could algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("based method algorithm"))) OR ("element could algorithm"))*.
