Perhaps you should try some spelling variations:
"complement based algorithms" » "complement past algorithms" (Expand Search), "complement cascade algorithms" (Expand Search), "complement system algorithms" (Expand Search), "complement based algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"elements box algorithm" » "elements best algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements b algorithm" (Expand Search), "elements upon 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 algorithms") OR ("elements box algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement based algorithms\") OR (\"elements box algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( complement based algorithms ) OR ( elements box algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement based algorithms") OR ("elements box algorithm"))) OR ("neural coding algorithm"))*.
