Perhaps you should try some spelling variations:
"client mining algorithm" » "client learning algorithm" (Expand Search), "client means algorithm" (Expand Search)
"element swarm algorithm" » "element search algorithm" (Expand Search), "element software 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)

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 em algorithm") OR ("element swarm algorithm"))) OR ("client mining algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element em algorithm\") OR (\"element swarm algorithm\"))) OR (\"client mining algorithm\"))".
• Removing quotes may allow a broader search: (((( element em algorithm ) OR ( element swarm algorithm ))) OR ( client mining algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element em algorithm") OR ("element swarm algorithm"))) OR ("client mining algorithm"))*.
