Perhaps you should try some spelling variations:
"post processing algorithm" » "post modeling algorithm" (Expand Search), "post tracking algorithm" (Expand Search), "post boosting algorithm" (Expand Search), "waste processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "food processing algorithm" (Expand Search)
"end routing algorithm" » "end modeling algorithm" (Expand Search), "end finding algorithm" (Expand Search), "end making algorithm" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "elements cnn 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 cnn algorithm") OR ((("post processing algorithm") OR ("end routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element cnn algorithm\") OR (((\"post processing algorithm\") OR (\"end routing algorithm\"))))".
• Removing quotes may allow a broader search: (( element cnn algorithm ) OR ((( post processing algorithm ) OR ( end routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element cnn algorithm") OR ((("post processing algorithm") OR ("end routing algorithm"))))*.
