Perhaps you should try some spelling variations:
"element matching algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "employment matching algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"effect tests algorithm" » "effect best algorithm" (Expand Search), "effect tested algorithms" (Expand Search), "effect means algorithm" (Expand Search), "effect test algorithm" (Expand Search), "effect results algorithm" (Expand Search), "exact tests 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 matching algorithm\") OR (\"element method algorithm\"))) OR (\"effect tests algorithm\"))~".
• Removing quotes may allow a broader search: (((( element matching algorithm ) OR ( element method algorithm ))) OR ( effect tests algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element matching algorithm") OR ("element method algorithm"))) OR ("effect tests algorithm"))*.
