Perhaps you should try some spelling variations:
"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)
"elements upon algorithms" » "elements two algorithms" (Expand Search), "elements nn algorithms" (Expand Search), "elements frog algorithms" (Expand Search), "elements ppm algorithms" (Expand Search), "elements uce algorithms" (Expand Search), "complements upon 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: (((("levels using algorithms") OR ("elements upon algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"levels using algorithms\") OR (\"elements upon algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( levels using algorithms ) OR ( elements upon algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("levels using algorithms") OR ("elements upon algorithms"))) OR ("neural coding algorithm"))*.
