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