Perhaps you should try some spelling variations:
"experiments show algorithm" » "experiments showed algorithm" (Expand Search), "experiments _ algorithm" (Expand Search), "experiments new algorithm" (Expand Search), "experiments pso algorithm" (Expand Search), "experiments box algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"elements ppo algorithm" » "elements pso algorithm" (Expand Search), "elements two algorithms" (Expand Search), "elements _ algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements upon 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 show algorithm") OR ("elements ppo algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments show algorithm\") OR (\"elements ppo algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments show algorithm ) OR ( elements ppo algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments show algorithm") OR ("elements ppo algorithm"))) OR ("neural coding algorithm"))*.
