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