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