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)
"movement data algorithms" » "movement art algorithms" (Expand Search), "movement all algorithms" (Expand Search), "movement both algorithms" (Expand Search)
"gmm clustering algorithm" » "_ clustering 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 ("gmm clustering algorithm"))) OR ("movement data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"gmm clustering algorithm\"))) OR (\"movement data algorithms\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( gmm clustering algorithm ))) OR ( movement data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("gmm clustering algorithm"))) OR ("movement data algorithms"))*.
