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 optimisation algorithmss" » "modified game optimization algorithms", "modified game estimation algorithms", "modified game estimation algorithm", "modified game optimization algorithmsss", "modified game estimation algorithmss", "modified game estimation algorithmsss", "modified game optimization algorithmss", "modified stage optimization algorithmss", "modified _ optimisation algorithmss", "modified male optimisation algorithmss", "modified adam optimisation 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 multiobjective optimisation algorithm") OR ("modified game optimisation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified game optimisation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified game optimisation algorithmss"))*.
