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

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

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