Perhaps you should try some spelling variations:
"elemental mapping algorithm" » "elemental sampling algorithm" (Expand Search), "elemental matching algorithm" (Expand Search), "elemental mining algorithm" (Expand Search), "elements mapping algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element ore algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("elemental mapping algorithm") OR ((("element mesh algorithm") OR ("element rf algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elemental mapping algorithm\") OR (((\"element mesh algorithm\") OR (\"element rf algorithm\"))))".
• Removing quotes may allow a broader search: (( elemental mapping algorithm ) OR ((( element mesh algorithm ) OR ( element rf algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elemental mapping algorithm") OR ((("element mesh algorithm") OR ("element rf algorithm"))))*.
