Perhaps you should try some spelling variations:
"dong optimized algorithms" » "dong optimizer algorithms", "dong optimization algorithms", "dong optimizer algorithmss", "cong optimized algorithms", "dung optimized algorithms"
"_ optimized algorithm" » "_ optimizer algorithms"
"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: (((("dong optimized algorithms") OR ("_ optimized algorithm"))) OR ("post estimation algorithm"))~.
• Removing quotes may allow a broader search: (((( dong optimized algorithms ) or ( _ optimized algorithm ))) or ( post estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dong optimized algorithms") or ("_ optimized algorithm"))) or ("post estimation algorithm"))*.
