Perhaps you should try some spelling variations:
"element method algorithm" » "element mould algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level colony algorithm" (Expand Search), "level scheduling algorithm" (Expand Search)
"element control algorithm" » "tolerant control 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 control algorithm\") OR (\"element method algorithm\"))) OR (\"level coding algorithm\"))~".
• Removing quotes may allow a broader search: (((( element control algorithm ) OR ( element method algorithm ))) OR ( level coding algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element control algorithm") OR ("element method algorithm"))) OR ("level coding algorithm"))*.
