Perhaps you should try some spelling variations:
"data routing algorithms" » "data routing algorithm" (Expand Search), "data sorting algorithms" (Expand Search), "data using algorithms" (Expand Search), "data groupings algorithms" (Expand Search), "data relating algorithms" (Expand Search)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"models using algorithm" » "models using algorithms" (Expand Search), "models routing algorithm" (Expand Search), "models fusion algorithm" (Expand Search), "model using 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: (("elements method algorithm") OR ((("data routing algorithms") OR ("models using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data routing algorithms\") OR (\"models using algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data routing algorithms ) OR ( models using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data routing algorithms") OR ("models using algorithm"))))*.
