Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"based method algorithm" » "based mould algorithm" (Expand Search)
"elements could algorithm" » "elements mould algorithm" (Expand Search), "elements carlo algorithm" (Expand Search), "elements colony algorithm" (Expand Search)

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 ("elements could algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"based method algorithm\"))) OR (\"elements could algorithm\"))*".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( based method algorithm ))) OR ( elements could algorithm ))*.
