Perhaps you should try some spelling variations:
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"prevalence data algorithm\"))) OR (\"data using algorithm\"))~".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( prevalence data algorithm ))) OR ( data using algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("prevalence data algorithm"))) OR ("data using algorithm"))*.
