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)
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element mining algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"client means algorithm" » "client search algorithm" (Expand Search), "client needs 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: (((("client learning algorithm") OR ("client means algorithm"))) OR ("element mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client learning algorithm\") OR (\"client means algorithm\"))) OR (\"element mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( client learning algorithm ) OR ( client means algorithm ))) OR ( element mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client learning algorithm") OR ("client means algorithm"))) OR ("element mapping algorithm"))*.
