Perhaps you should try some spelling variations:
"element controls algorithm" » "element control algorithm" (Expand Search), "elements controls algorithm" (Expand Search)
"neural modeling algorithm" » "neural scheduling algorithm" (Expand Search)
"complement _ algorithm" » "implement _ algorithm" (Expand Search), "complementary _ 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 _ algorithm") OR ("element controls algorithm"))) OR ("neural modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement _ algorithm\") OR (\"element controls algorithm\"))) OR (\"neural modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( complement _ algorithm ) OR ( element controls algorithm ))) OR ( neural modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement _ algorithm") OR ("element controls algorithm"))) OR ("neural modeling algorithm"))*.
