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