Perhaps you should try some spelling variations:
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping 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)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: "((((\"prevalence data algorithm\") OR (\"element data algorithm\"))) OR (\"element mapping algorithm\"))~".
• Removing quotes may allow a broader search: (((( prevalence data algorithm ) OR ( element data algorithm ))) OR ( element mapping algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("prevalence data algorithm") OR ("element data algorithm"))) OR ("element mapping algorithm"))*.
