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

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

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