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