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