Perhaps you should try some spelling variations:
"experiment showed algorithm" » "experiment mould algorithm" (Expand Search), "experiments showed algorithm" (Expand Search), "experimental showed algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"movement data algorithm" » "movement jaya algorithm" (Expand Search), "movement deer 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: (((("experiment showed algorithm") OR ("movement data algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiment showed algorithm\") OR (\"movement data algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experiment showed algorithm ) OR ( movement data algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiment showed algorithm") OR ("movement data algorithm"))) OR ("neural coding algorithm"))*.
