Perhaps you should try some spelling variations:
"select controls algorithm" » "select control algorithm" (Expand Search), "selected controls algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"element cnn algorithm" » "element rd algorithm" (Expand Search), "element colony algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements cnn algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cnn algorithm\") OR (\"select controls algorithm\"))) OR (\"neural coding algorithm\"))~".
• Removing quotes may allow a broader search: (((( element cnn algorithm ) OR ( select controls algorithm ))) OR ( neural coding algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element cnn algorithm") OR ("select controls algorithm"))) OR ("neural coding algorithm"))*.
