Perhaps you should try some spelling variations:
"experimental based algorithm" » "experimental case algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experiments based algorithm" (Expand Search)
"tests using algorithms" » "tests pacing algorithms" (Expand Search), "tests nine algorithms" (Expand Search), "tests sorting algorithms" (Expand Search), "tested using algorithms" (Expand Search), "results using algorithms" (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: (((("experimental based algorithm") OR ("tests using algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experimental based algorithm\") OR (\"tests using algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experimental based algorithm ) OR ( tests using algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experimental based algorithm") OR ("tests using algorithms"))) OR ("neural coding algorithm"))*.
