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 two algorithms" » "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element art algorithms" (Expand Search), "element te algorithms" (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: (((("data processing algorithm") OR ("forest modeling algorithm"))) OR ("element two algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"forest modeling algorithm\"))) OR (\"element two algorithms\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( forest modeling algorithm ))) OR ( element two algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("forest modeling algorithm"))) OR ("element two algorithms"))*.
