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