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