Perhaps you should try some spelling variations:
"frequent making algorithm" » "frequent cosine algorithm" (Expand Search), "frequently making algorithm" (Expand Search), "frequency making algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"element tree algorithms" » "elements tree algorithms" (Expand Search), "element three algorithms" (Expand Search), "element free algorithms" (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: (("element tree algorithms") OR ((("frequent making algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tree algorithms\") OR (((\"frequent making algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element tree algorithms ) OR ((( frequent making algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element tree algorithms") OR ((("frequent making algorithm") OR ("neural coding algorithm"))))*.
