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