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)
"element pass algorithm" » "element lasso algorithm" (Expand Search), "element pso algorithm" (Expand Search), "element rast algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 ((("element pass algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"complement based algorithm\") OR (((\"element pass algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( complement based algorithm ) OR ((( element pass algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("complement based algorithm") OR ((("element pass algorithm") OR ("neural coding algorithm"))))*.
