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