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

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

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