Perhaps you should try some spelling variations:
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"element both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh 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 both algorithms") OR ("element based algorithms"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element both algorithms\") OR (\"element based algorithms\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( element both algorithms ) OR ( element based algorithms ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element both algorithms") OR ("element based algorithms"))) OR ("data using algorithm"))*.
