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