Perhaps you should try some spelling variations:
"parameters optimization algorithmss" » "parameters optimization algorithms", "parameters optimisation algorithm", "parameters estimation algorithms", "parameter optimization algorithmss", "parameter estimation algorithmss", "parameters optimization algorithmsss", "parameters optimisation algorithmss", "parameters estimation algorithmss"
"qoe optimization algorithm" » "qoe optimization algorithms", "qoe optimisation algorithm", "qoe estimation algorithm", "game optimization algorithm", "_ optimization algorithm", "stage optimization 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: (("qoe optimization algorithm") OR ("parameters optimization algorithmss"))~.
• Removing quotes may allow a broader search: (( qoe optimization algorithm ) or ( parameters optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("qoe optimization algorithm") or ("parameters optimization algorithmss"))*.
