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