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