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