Perhaps you should try some spelling variations:
"modified qoe optimization algorithm" » "modified qoe optimization algorithms", "modified qoe optimisation algorithm", "modified qoe estimation algorithm", "modified game optimization algorithm", "modified _ optimization algorithm", "modified stage optimization algorithm", "modified male optimization algorithm", "modified bi1 optimization algorithm"
"modified parameter optimized algorithms" » "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization 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 algorithm") OR ("modified parameter optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified qoe optimization algorithm ) or ( modified parameter optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified qoe optimization algorithm") or ("modified parameter optimized algorithms"))*.
