Perhaps you should try some spelling variations:
"client learning algorithm" » "client learning algorithms" (Expand Search), "student learning algorithm" (Expand Search)
"elements sampling algorithm" » "elements scheduling algorithm" (Expand Search)
"line search algorithm" » "line research algorithm" (Expand Search)

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 ("line search algorithm"))) OR ("elements sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client learning algorithm\") OR (\"line search algorithm\"))) OR (\"elements sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( client learning algorithm ) OR ( line search algorithm ))) OR ( elements sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client learning algorithm") OR ("line search algorithm"))) OR ("elements sampling algorithm"))*.
