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