Perhaps you should try some spelling variations:
"element network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"experiments based algorithm" » "experiments showed algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experimental case algorithm" (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 network algorithm") OR ("experiments based algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element network algorithm\") OR (\"experiments based algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( element network algorithm ) OR ( experiments based algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element network algorithm") OR ("experiments based algorithm"))) OR ("data using algorithm"))*.
