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

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