Perhaps you should try some spelling variations:
"element software algorithm" » "element swarm algorithm" (Expand Search)
"client mining algorithm" » "client learning algorithm" (Expand Search), "client means algorithm" (Expand Search)
"element study algorithm" » "present study algorithm" (Expand Search), "recent study algorithm" (Expand Search), "event study 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 study algorithm") OR ("element software algorithm"))) OR ("client mining algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element study algorithm\") OR (\"element software algorithm\"))) OR (\"client mining algorithm\"))".
• Removing quotes may allow a broader search: (((( element study algorithm ) OR ( element software algorithm ))) OR ( client mining algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element study algorithm") OR ("element software algorithm"))) OR ("client mining algorithm"))*.
