Perhaps you should try some spelling variations:
"data processin_ algorithm" » "data processing algorithm" (Expand Search), "data present algorithm" (Expand Search), "data promising algorithms" (Expand Search), "data preprocessing algorithm" (Expand Search), "waste processing algorithm" (Expand Search)
"element em algorithm" » "element new algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element _ algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element te algorithm" (Expand Search)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "element te 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 processin_ algorithm") OR ((("element em algorithm") OR ("element g algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processin_ algorithm\") OR (((\"element em algorithm\") OR (\"element g algorithm\"))))".
• Removing quotes may allow a broader search: (( data processin_ algorithm ) OR ((( element em algorithm ) OR ( element g algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processin_ algorithm") OR ((("element em algorithm") OR ("element g algorithm"))))*.
