Perhaps you should try some spelling variations:
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"pigment control algorithm" » "pigment contents algorithm" (Expand Search), "element controls 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: (((("pigment control algorithm") OR ("movement data algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"pigment control algorithm\") OR (\"movement data algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( pigment control algorithm ) OR ( movement data algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("pigment control algorithm") OR ("movement data algorithms"))) OR ("neural coding algorithm"))*.
