Perhaps you should try some spelling variations:
"data routing algorithm" » "data cosine algorithm" (Expand Search), "data using algorithm" (Expand Search)
"improvements using algorithm" » "improvements cosine algorithm" (Expand Search), "improvement using algorithm" (Expand Search)
"element data algorithm" » "element jaya algorithm" (Expand Search), "element deer algorithm" (Expand Search), "elements data algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("improvements using algorithm") OR ("element data algorithm"))) OR ("data routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"improvements using algorithm\") OR (\"element data algorithm\"))) OR (\"data routing algorithm\"))".
• Removing quotes may allow a broader search: (((( improvements using algorithm ) OR ( element data algorithm ))) OR ( data routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("improvements using algorithm") OR ("element data algorithm"))) OR ("data routing algorithm"))*.
