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