Perhaps you should try some spelling variations:
"pulses estimation algorithms" » "pulses estimation algorithm", "pulses optimization algorithms", "pulses optimisation algorithm", "pose 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: (("pulses estimation algorithms") or ((("qoe optimized algorithm") or ("_ optimized algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("pulses estimation algorithms") OR ((("qoe optimized algorithm") OR ("_ optimized algorithms")))).
• Removing quotes may allow a broader search: (( pulses estimation algorithms ) or ((( qoe optimized algorithm ) or ( _ optimized algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("pulses estimation algorithms") or ((("qoe optimized algorithm") or ("_ optimized algorithms"))))*.
