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