Perhaps you should try some spelling variations:
"models using algorithms" » "models pacing algorithms" (Expand Search), "models nine algorithms" (Expand Search), "models sorting algorithms" (Expand Search), "model using algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"experiments pso algorithm" » "experiments also algorithm" (Expand Search), "experiments p algorithm" (Expand Search), "experiments ns algorithm" (Expand Search), "experiments lasso algorithm" (Expand Search), "experiments _ algorithm" (Expand Search), "experiments ii 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 pso algorithm") OR ("models using algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments pso algorithm\") OR (\"models using algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments pso algorithm ) OR ( models using algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments pso algorithm") OR ("models using algorithms"))) OR ("neural coding algorithm"))*.
