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)
"model using algorithm" » "model using algorithms" (Expand Search), "model routing algorithm" (Expand Search), "model fusion algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement atlas 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: (((("data processing algorithm") OR ("model using algorithm"))) OR ("settlement data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"model using algorithm\"))) OR (\"settlement data algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( model using algorithm ))) OR ( settlement data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("model using algorithm"))) OR ("settlement data algorithm"))*.
