Perhaps you should try some spelling variations:
"experiments based algorithm" » "experiments showed algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experimental case algorithm" (Expand Search)
"levels using algorithms" » "levels pacing algorithms" (Expand Search), "levels nine algorithms" (Expand Search), "levels sorting algorithms" (Expand Search), "level using algorithms" (Expand Search), "models using algorithms" (Expand Search), "cells using algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("experiments based algorithm") OR ("levels using algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments based algorithm\") OR (\"levels using algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments based algorithm ) OR ( levels using algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments based algorithm") OR ("levels using algorithms"))) OR ("neural coding algorithm"))*.
