Perhaps you should try some spelling variations:
"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)
"element each algorithm" » "element search algorithm" (Expand Search), "element em algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 each algorithm") OR ("element mapping algorithm"))) OR ("client means algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element each algorithm\") OR (\"element mapping algorithm\"))) OR (\"client means algorithm\"))".
• Removing quotes may allow a broader search: (((( element each algorithm ) OR ( element mapping algorithm ))) OR ( client means algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element each algorithm") OR ("element mapping algorithm"))) OR ("client means algorithm"))*.
