Perhaps you should try some spelling variations:
"qoe optimization algorithmss" » "qoe optimization algorithms", "qoe optimisation algorithm", "qoe estimation algorithms", "qoe optimization algorithmsss", "qoe optimisation algorithmss", "qoe estimation algorithmss", "game optimization algorithmss", "_ optimization algorithmss", "stage optimization algorithmss"
"parameters optimization algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameters optimization algorithms", "parameters optimisation algorithm", "parameters estimation algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("parameters optimization algorithm") OR ("qoe optimization algorithmss"))~.
• Removing quotes may allow a broader search: (( parameters optimization algorithm ) or ( qoe optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("parameters optimization algorithm") or ("qoe optimization algorithmss"))*.
