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