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)
"client mining algorithm" » "client finding algorithm" (Expand Search), "client making algorithm" (Expand Search), "client training algorithms" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te 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 mesh algorithm"))) OR ("client mining algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments based algorithm\") OR (\"element mesh algorithm\"))) OR (\"client mining algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments based algorithm ) OR ( element mesh algorithm ))) OR ( client mining algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments based algorithm") OR ("element mesh algorithm"))) OR ("client mining algorithm"))*.
