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