Perhaps you should try some spelling variations:
"dong optimized algorithm" » "dong optimized algorithms", "dong optimizer algorithms", "cong optimized algorithm", "dung optimized algorithm"
"cost optimized algorithm" » "cost optimized algorithms", "cost optimizer algorithms", "most optimized algorithm"
"risk estimation algorithm" » "pose estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("dong optimized algorithm") or ("cost optimized algorithm"))) or ("risk estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("dong optimized algorithm") OR ("cost optimized algorithm"))) OR ("risk estimation algorithm")).
• Removing quotes may allow a broader search: (((( dong optimized algorithm ) or ( cost optimized algorithm ))) or ( risk estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("dong optimized algorithm") or ("cost optimized algorithm"))) or ("risk estimation algorithm"))*.
