Perhaps you should try some spelling variations:
"experiments based algorithm" » "experiments showed algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experimental case algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (Expand Search)
"levels using algorithm" » "levels using algorithms" (Expand Search), "levels routing algorithm" (Expand Search), "levels fusion algorithm" (Expand Search), "level using algorithm" (Expand Search), "models using algorithm" (Expand Search), "cells using 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: (((("experiments based algorithm") OR ("element data algorithms"))) OR ("levels using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments based algorithm\") OR (\"element data algorithms\"))) OR (\"levels using algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments based algorithm ) OR ( element data algorithms ))) OR ( levels using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments based algorithm") OR ("element data algorithms"))) OR ("levels using algorithm"))*.
