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)
"elements cscap algorithm" » "elements cc3d algorithm" (Expand Search), "elements ipca algorithm" (Expand Search), "elements custom algorithm" (Expand Search), "elements crcy 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)

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: (((("elements cscap algorithm") OR ("experiments based algorithm"))) OR ("level using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements cscap algorithm\") OR (\"experiments based algorithm\"))) OR (\"level using algorithm\"))".
• Removing quotes may allow a broader search: (((( elements cscap algorithm ) OR ( experiments based algorithm ))) OR ( level using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements cscap algorithm") OR ("experiments based algorithm"))) OR ("level using algorithm"))*.
