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