Perhaps you should try some spelling variations:
"post processingnb algorithm" » "post processing algorithm" (Expand Search), "list processing algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii 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: (("post processingnb algorithm") OR ((("element cnn algorithm") OR ("relevant data algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"post processingnb algorithm\") OR (((\"element cnn algorithm\") OR (\"relevant data algorithms\"))))".
• Removing quotes may allow a broader search: (( post processingnb algorithm ) OR ((( element cnn algorithm ) OR ( relevant data algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("post processingnb algorithm") OR ((("element cnn algorithm") OR ("relevant data algorithms"))))*.
