Perhaps you should try some spelling variations:
"complement cosine algorithm" » "complement colony algorithm" (Expand Search)
"neural coding algorithm" » "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"elements pso algorithm" » "elements _ algorithm" (Expand Search), "elementi per algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("elements pso algorithm") OR ("complement cosine algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements pso algorithm\") OR (\"complement cosine algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements pso algorithm ) OR ( complement cosine algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements pso algorithm") OR ("complement cosine algorithm"))) OR ("neural coding algorithm"))*.
