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