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)
"elements small algorithm" » "elements all algorithms" (Expand Search), "elements mlm algorithm" (Expand Search), "elements sac 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 swarm algorithm") OR ("elements small algorithm"))) OR ("client mining algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element swarm algorithm\") OR (\"elements small algorithm\"))) OR (\"client mining algorithm\"))".
• Removing quotes may allow a broader search: (((( element swarm algorithm ) OR ( elements small algorithm ))) OR ( client mining algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element swarm algorithm") OR ("elements small algorithm"))) OR ("client mining algorithm"))*.
