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)
"present within algorithm" » "present switching algorithm" (Expand Search), "present twisting algorithm" (Expand Search), "present finding algorithm" (Expand Search)
"element ree algorithm" » "element tree algorithms" (Expand Search), "element new algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements res algorithm" (Expand Search), "element te 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: (("element ree algorithm") OR ((("present within algorithm") OR ("element matching algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element ree algorithm\") OR (((\"present within algorithm\") OR (\"element matching algorithm\"))))".
• Removing quotes may allow a broader search: (( element ree algorithm ) OR ((( present within algorithm ) OR ( element matching algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element ree algorithm") OR ((("present within algorithm") OR ("element matching algorithm"))))*.
