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