Perhaps you should try some spelling variations:
"element boosting algorithm" » "element routing algorithm" (Expand Search), "element twisting algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element bonding 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 crcy algorithm" » "elements carlo algorithm" (Expand Search), "elements cscap algorithm" (Expand Search), "elements each 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: (((("element boosting algorithm") OR ("elements crcy algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element boosting algorithm\") OR (\"elements crcy algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element boosting algorithm ) OR ( elements crcy algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element boosting algorithm") OR ("elements crcy algorithm"))) OR ("level coding algorithm"))*.
