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)
"element cc3d algorithm" » "element cscap algorithm" (Expand Search), "element cnn algorithm" (Expand Search), "element wold algorithm" (Expand Search), "elements cc3d 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: (((("element cc3d algorithm") OR ("settlement data algorithm"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cc3d algorithm\") OR (\"settlement data algorithm\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element cc3d algorithm ) OR ( settlement data algorithm ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element cc3d algorithm") OR ("settlement data algorithm"))) OR ("data processing algorithm"))*.
