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)
"element both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh algorithms" (Expand Search)
"system using algorithm" » "system using algorithms" (Expand Search), "system routing algorithm" (Expand Search), "system fusion 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 both algorithms") OR ((("data processing algorithm") OR ("system using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element both algorithms\") OR (((\"data processing algorithm\") OR (\"system using algorithm\"))))".
• Removing quotes may allow a broader search: (( element both algorithms ) OR ((( data processing algorithm ) OR ( system using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element both algorithms") OR ((("data processing algorithm") OR ("system using algorithm"))))*.
