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