Perhaps you should try some spelling variations:
"experiments showed algorithm" » "experiments mould algorithm" (Expand Search), "experimental showed algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"relevant new algorithm" » "relevant deer algorithm" (Expand Search), "relevant rd algorithm" (Expand Search), "relevent le 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: (((("experiments showed algorithm") OR ("relevant new algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments showed algorithm\") OR (\"relevant new algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments showed algorithm ) OR ( relevant new algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments showed algorithm") OR ("relevant new algorithm"))) OR ("neural coding algorithm"))*.
