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)
"flow modeling algorithm" » "flow making algorithm" (Expand Search), "low modeling algorithm" (Expand Search)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based 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 ("flow modeling algorithm"))) OR ("element based algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"flow modeling algorithm\"))) OR (\"element based algorithms\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( flow modeling algorithm ))) OR ( element based algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("flow modeling algorithm"))) OR ("element based algorithms"))*.
