Perhaps you should try some spelling variations:
"complement based algorithm" » "complement past algorithm" (Expand Search), "complement cascade algorithm" (Expand Search), "complement system algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"second model algorithm" » "second novel algorithm" (Expand Search), "second modbo algorithm" (Expand Search), "second modeling algorithm" (Expand Search), "second module algorithm" (Expand Search), "second order algorithm" (Expand Search), "second dose 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: (("complement based algorithm") OR ((("second model algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"complement based algorithm\") OR (((\"second model algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( complement based algorithm ) OR ((( second model algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("complement based algorithm") OR ((("second model algorithm") OR ("neural coding algorithm"))))*.
