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