Perhaps you should try some spelling variations:
"modified qoe optimization algorithms" » "modified qoe optimisation algorithm", "modified qoe estimation algorithms", "modified qoe estimation algorithm", "modified qoe optimisation algorithms", "modified qoe estimation algorithmss", "modified game optimization algorithms", "modified _ optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms", "modified bi1 optimization algorithms"
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters estimation algorithms"

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: (("modified qoe optimization algorithms") OR ("modified parameters optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified qoe optimization algorithms ) or ( modified parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified qoe optimization algorithms") or ("modified parameters optimization algorithm"))*.
