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)
"scale matching algorithm" » "scale making algorithm" (Expand Search), "scale modeling algorithm" (Expand Search), "scale mining algorithm" (Expand Search), "score matching algorithm" (Expand Search), "case matching algorithm" (Expand Search), "scale machine algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 ("scale matching algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"scale matching algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( scale matching algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("scale matching algorithm"))) OR ("element method algorithm"))*.
