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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("qoe optimized algorithms") OR ("_ optimized algorithmss"))) OR ("post estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe optimized algorithms\") OR (\"_ optimized algorithmss\"))) OR (\"post estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( qoe optimized algorithms ) OR ( _ optimized algorithmss ))) OR ( post estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimized algorithms") OR ("_ optimized algorithmss"))) OR ("post estimation algorithms"))*.
