Perhaps you should try some spelling variations:
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element mining algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element modbo algorithm" (Expand Search)
"effects means algorithm" » "effects search algorithm" (Expand Search), "effective means algorithm" (Expand Search), "effects meta algorithm" (Expand Search), "effects ames 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: (((("element mapping algorithm") OR ("element method algorithm"))) OR ("effects means algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mapping algorithm\") OR (\"element method algorithm\"))) OR (\"effects means algorithm\"))".
• Removing quotes may allow a broader search: (((( element mapping algorithm ) OR ( element method algorithm ))) OR ( effects means algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mapping algorithm") OR ("element method algorithm"))) OR ("effects means algorithm"))*.
