Perhaps you should try some spelling variations:
"data boosting algorithm" » "data cosine algorithm" (Expand Search)
"joint modeling algorithm" » "joint scheduling algorithm" (Expand Search), "agent modeling algorithm" (Expand Search), "event modeling algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method 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 boosting algorithm") OR ("joint modeling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data boosting algorithm\") OR (\"joint modeling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data boosting algorithm ) OR ( joint modeling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data boosting algorithm") OR ("joint modeling algorithm"))) OR ("element method algorithm"))*.
