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 coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"elements over algorithm" » "elements novel algorithm" (Expand Search), "elements other algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements under algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "events over 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 over algorithm") OR ("experiments based algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements over algorithm\") OR (\"experiments based algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements over algorithm ) OR ( experiments based algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements over algorithm") OR ("experiments based algorithm"))) OR ("level coding algorithm"))*.
