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