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