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