Perhaps you should try some spelling variations:
"element content algorithm" » "element control algorithm" (Expand Search), "element colony algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements content algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level colony algorithm" (Expand Search), "level scheduling algorithm" (Expand Search)
"implement based algorithm" » "implemented based algorithm" (Expand Search), "implementing based algorithm" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("implement based algorithm") OR ("element content algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement based algorithm\") OR (\"element content algorithm\"))) OR (\"level coding algorithm\"))*".
• Removing quotes may allow a broader search: (((( implement based algorithm ) OR ( element content algorithm ))) OR ( level coding algorithm ))*.
