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