Perhaps you should try some spelling variations:
"scale processing algorithm" » "scale processing algorithms" (Expand Search), "image processing algorithm" (Expand Search), "signal processing algorithm" (Expand Search), "melt processing algorithm" (Expand Search)
"data using algorithm" » "data cosine algorithm" (Expand Search)
"element network algorithm" » "elements network 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 network algorithm") OR ((("data using algorithm") OR ("scale processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element network algorithm\") OR (((\"data using algorithm\") OR (\"scale processing algorithm\"))))".
• Removing quotes may allow a broader search: (( element network algorithm ) OR ((( data using algorithm ) OR ( scale processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element network algorithm") OR ((("data using algorithm") OR ("scale processing algorithm"))))*.
