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)
"events using algorithms" » "events pacing algorithms" (Expand Search), "events nine algorithms" (Expand Search), "events sorting algorithms" (Expand Search), "tests using algorithms" (Expand Search), "genes using algorithms" (Expand Search), "levels 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: (((("experiments show algorithm") OR ("events using algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments show algorithm\") OR (\"events using algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments show algorithm ) OR ( events using algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments show algorithm") OR ("events using algorithms"))) OR ("neural coding algorithm"))*.
