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)
"element mean algorithm" » "element means algorithm" (Expand Search), "element new algorithm" (Expand Search), "element each algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "latent mean algorithm" (Expand Search), "element te 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: (((("element mean algorithm") OR ("models using algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mean algorithm\") OR (\"models using algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element mean algorithm ) OR ( models using algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mean algorithm") OR ("models using algorithms"))) OR ("neural coding algorithm"))*.
