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