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)
"prevalence data algorithm" » "prevalence rate algorithm" (Expand Search), "prevalence rates algorithm" (Expand Search), "prevalence ratio algorithm" (Expand Search), "prevalence data algorithms" (Expand Search), "prevalence update algorithm" (Expand Search), "prevalence atlas algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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 ("prevalence data algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"prevalence data algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( prevalence data algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("prevalence data algorithm"))) OR ("data using algorithm"))*.
