Perhaps you should try some spelling variations:
"reduced learning algorithm" » "reduced learning algorithms" (Expand Search), "reduce learning algorithm" (Expand Search)
"tested using algorithms" » "tested cosine algorithm" (Expand Search), "system using algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling 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: (("tested using algorithms") OR ((("reduced learning algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tested using algorithms\") OR (((\"reduced learning algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( tested using algorithms ) OR ((( reduced learning algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("tested using algorithms") OR ((("reduced learning algorithm") OR ("neural coding algorithm"))))*.
