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