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)
"level using algorithm" » "level using algorithms" (Expand Search), "level routing algorithm" (Expand Search), "level fusion algorithm" (Expand Search), "levels using algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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 algorithm"))) OR ("level using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments based algorithm\") OR (\"element data algorithm\"))) OR (\"level using algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments based algorithm ) OR ( element data algorithm ))) OR ( level using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments based algorithm") OR ("element data algorithm"))) OR ("level using algorithm"))*.
