Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"elements method algorithms" » "elements two algorithms" (Expand Search), "elements both algorithms" (Expand Search), "elements other algorithms" (Expand Search), "element method 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 algorithms") OR ("presence data algorithm"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithms\") OR (\"presence data algorithm\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithms ) OR ( presence data algorithm ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithms") OR ("presence data algorithm"))) OR ("data modeling algorithm"))*.
