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