Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"modified game optimization algorithmss" » "modified game optimization algorithms", "modified game estimation algorithms", "modified game estimation algorithm", "modified stage optimization algorithmss", "modified qoe optimization algorithmss", "modified market optimization algorithmss", "modified male optimization algorithmss", "modified adam optimization algorithmss"

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