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 means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"effects test algorithm" » "effects best algorithm" (Expand Search), "effects forest algorithm" (Expand Search), "effects new algorithm" (Expand Search), "effect test algorithm" (Expand Search), "effect tests algorithm" (Expand Search), "effects must 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 means algorithm"))) OR ("effects test algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mapping algorithm\") OR (\"element means algorithm\"))) OR (\"effects test algorithm\"))".
• Removing quotes may allow a broader search: (((( element mapping algorithm ) OR ( element means algorithm ))) OR ( effects test algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mapping algorithm") OR ("element means algorithm"))) OR ("effects test algorithm"))*.
