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