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