Perhaps you should try some spelling variations:
"modified invasive optimizer algorithmss" » "modified invasive optimized algorithms", "modified invasive optimized algorithm", "modified invasive optimized algorithmss", "modified invasive optimization algorithmss", "modified passive optimizer algorithmss"
"modified parameter optimizer algorithms" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimization algorithms"

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 invasive optimizer algorithmss") OR ("modified parameter optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( modified invasive optimizer algorithmss ) or ( modified parameter optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive optimizer algorithmss") or ("modified parameter optimizer algorithms"))*.
