Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithmss" » "modified multiobjective optimization algorithmss", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimization algorithms"
"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"

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