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