Perhaps you should try some spelling variations:
"relevant update algorithm" » "relevant pass algorithm" (Expand Search), "relevant data algorithms" (Expand Search), "relevant ipca algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "relevant rate algorithm" (Expand Search)
"level using algorithms" » "level pacing algorithms" (Expand Search), "level nine algorithms" (Expand Search), "level sorting algorithms" (Expand Search), "levels using algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding 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 update algorithm") OR ("level using algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant update algorithm\") OR (\"level using algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant update algorithm ) OR ( level using algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant update algorithm") OR ("level using algorithms"))) OR ("neural coding algorithm"))*.
