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 passive solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline solution 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 passive solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified qoe optimization algorithms ) or ( modified passive solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified qoe optimization algorithms") or ("modified passive solution algorithm"))*.
