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