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