Perhaps you should try some spelling variations:
"relevant data algorithm" » "relevant jaya algorithm" (Expand Search), "relevant deer algorithm" (Expand Search)
"implement based algorithm" » "implemented based algorithm" (Expand Search), "implementing based algorithm" (Expand Search)
"element network algorithm" » "elements network 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: (("implement based algorithm") OR ((("relevant data algorithm") OR ("element network algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement based algorithm\") OR (((\"relevant data algorithm\") OR (\"element network algorithm\"))))".
• Removing quotes may allow a broader search: (( implement based algorithm ) OR ((( relevant data algorithm ) OR ( element network algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement based algorithm") OR ((("relevant data algorithm") OR ("element network algorithm"))))*.
