Perhaps you should try some spelling variations:
"element scraping algorithm" » "element making algorithm" (Expand Search), "element sorting algorithms" (Expand Search), "element tracking algorithm" (Expand Search), "element strain algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"present study algorithm" » "present wsindy algorithm" (Expand Search), "present td3 algorithm" (Expand Search), "present seu 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 ((("relevant data algorithms") OR ("present study algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element scraping algorithm\") OR (((\"relevant data algorithms\") OR (\"present study algorithm\"))))".
• Removing quotes may allow a broader search: (( element scraping algorithm ) OR ((( relevant data algorithms ) OR ( present study algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element scraping algorithm") OR ((("relevant data algorithms") OR ("present study algorithm"))))*.
