Perhaps you should try some spelling variations:
"post processingnb algorithm" » "post processing algorithm" (Expand Search), "list processing algorithm" (Expand Search)
"element te algorithm" » "element tide algorithm" (Expand Search), "element new algorithm" (Expand Search), "element de algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ 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 g algorithm") OR ("element te algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"post processingnb algorithm\") OR (((\"element g algorithm\") OR (\"element te algorithm\"))))".
• Removing quotes may allow a broader search: (( post processingnb algorithm ) OR ((( element g algorithm ) OR ( element te algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("post processingnb algorithm") OR ((("element g algorithm") OR ("element te algorithm"))))*.
