Perhaps you should try some spelling variations:
"data preprocessinb algorithm" » "data processing algorithm" (Expand Search), "data preprocessing algorithm" (Expand Search), "dataset preprocessing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element fbe algorithm" » "element b algorithm" (Expand Search), "element dbo algorithm" (Expand Search), "element abs algorithm" (Expand Search), "element te algorithm" (Expand Search), "elements fe algorithm" (Expand Search), "element ore 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 method algorithm") OR ("element fbe algorithm"))) OR ("data preprocessinb algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"element fbe algorithm\"))) OR (\"data preprocessinb algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( element fbe algorithm ))) OR ( data preprocessinb algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("element fbe algorithm"))) OR ("data preprocessinb algorithm"))*.
