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 algorithms" » "_ optimizer algorithms", "_ optimization algorithms", "_ optimizer algorithmss"
"qoe optimized algorithm" » "qoe optimizer algorithms"

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

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