Perhaps you should try some spelling variations:
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)
"presence data algorithm" » "presence data algorithms" (Expand Search), "presence update algorithm" (Expand Search), "presence atlas algorithm" (Expand Search), "prevalence data algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("elements method algorithm") OR ("presence data algorithm"))) OR ("data using algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"presence data algorithm\"))) OR (\"data using algorithms\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( presence data algorithm ))) OR ( data using algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("presence data algorithm"))) OR ("data using algorithms"))*.
