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