Perhaps you should try some spelling variations:
"element matching algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "employment matching algorithm" (Expand Search)
"presence data algorithms" » "presence art algorithms" (Expand Search), "presence all algorithms" (Expand Search), "presence both algorithms" (Expand Search), "presence update algorithms" (Expand Search), "presence atlas algorithms" (Expand Search), "presence each algorithms" (Expand Search), "prevalence data algorithms" (Expand Search)
"element data algorithm" » "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "element each algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (((("presence data algorithms") OR ("element data algorithm"))) OR ("element matching algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"presence data algorithms\") OR (\"element data algorithm\"))) OR (\"element matching algorithm\"))".
• Removing quotes may allow a broader search: (((( presence data algorithms ) OR ( element data algorithm ))) OR ( element matching algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("presence data algorithms") OR ("element data algorithm"))) OR ("element matching algorithm"))*.
