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