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