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