Perhaps you should try some spelling variations:
"implement cosine algorithm" » "implement routine algorithm" (Expand Search), "implement colony algorithm" (Expand Search), "implement routing algorithm" (Expand Search), "implement fusion algorithm" (Expand Search)
"neural coding algorithm" » "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search), "neural routing algorithm" (Expand Search)
"elements pso algorithm" » "elements lasso algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii 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: (("elements pso algorithm") OR ((("implement cosine algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements pso algorithm\") OR (((\"implement cosine algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements pso algorithm ) OR ((( implement cosine algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements pso algorithm") OR ((("implement cosine algorithm") OR ("neural coding algorithm"))))*.
