Perhaps you should try some spelling variations:
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level colony algorithm" (Expand Search), "level scheduling algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "elements means algorithm" (Expand Search)
"experiments using algorithm" » "experiments cosine algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

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