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)
"based mapping algorithm" » "based making algorithm" (Expand Search), "based mining algorithm" (Expand Search), "based learning algorithm" (Expand Search), "based machine algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (((("based mapping algorithm") OR ("data processing algorithm"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"based mapping algorithm\") OR (\"data processing algorithm\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( based mapping algorithm ) OR ( data processing algorithm ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("based mapping algorithm") OR ("data processing algorithm"))) OR ("element data algorithm"))*.
