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