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 strain algorithm" » "element scraping algorithm" (Expand Search), "element tracking algorithm" (Expand Search), "element swarm algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh 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 strain algorithm") OR ((("element mapping algorithm") OR ("element means algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element strain algorithm\") OR (((\"element mapping algorithm\") OR (\"element means algorithm\"))))".
• Removing quotes may allow a broader search: (( element strain algorithm ) OR ((( element mapping algorithm ) OR ( element means algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element strain algorithm") OR ((("element mapping algorithm") OR ("element means algorithm"))))*.
