Perhaps you should try some spelling variations:
"experiments using algorithm" » "experiments show algorithm" (Expand Search), "experimental testing algorithm" (Expand Search), "experiments using algorithms" (Expand Search), "experiments routing algorithm" (Expand Search), "experiments fusion 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 best algorithm" » "elements forest algorithm" (Expand Search), "elements based algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements res algorithm" (Expand Search), "elements b 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 best algorithm") OR ("experiments using algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements best algorithm\") OR (\"experiments using algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements best algorithm ) OR ( experiments using algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements best algorithm") OR ("experiments using algorithm"))) OR ("level coding algorithm"))*.
