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