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