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