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