Perhaps you should try some spelling variations:
"select control algorithms" » "select control algorithm" (Expand Search), "selected control algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"complement em algorithm" » "complement deer algorithm" (Expand Search), "implement em algorithm" (Expand Search), "complementary em 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 em algorithm") OR ("select control algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement em algorithm\") OR (\"select control algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( complement em algorithm ) OR ( select control algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement em algorithm") OR ("select control algorithms"))) OR ("neural coding algorithm"))*.
