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