Perhaps you should try some spelling variations:
"elements learning algorithm" » "elements learning algorithms" (Expand Search), "students learning algorithm" (Expand Search), "elements during algorithm" (Expand Search)
"client needs algorithm" » "client means algorithm" (Expand Search), "client new algorithm" (Expand Search), "client leiden algorithm" (Expand Search), "china needs algorithm" (Expand Search)
"urgent needs algorithm" » "urgent means algorithm" (Expand Search), "urgent new algorithm" (Expand Search), "urgent leiden algorithm" (Expand Search), "urgent need algorithm" (Expand Search), "unmet needs 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 needs algorithm") OR ("urgent needs algorithm"))) OR ("elements learning algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client needs algorithm\") OR (\"urgent needs algorithm\"))) OR (\"elements learning algorithm\"))".
• Removing quotes may allow a broader search: (((( client needs algorithm ) OR ( urgent needs algorithm ))) OR ( elements learning algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client needs algorithm") OR ("urgent needs algorithm"))) OR ("elements learning algorithm"))*.
