Perhaps you should try some spelling variations:
"modified passive optimization algorithms" » "modified passive optimisation algorithm", "modified passive estimation algorithms", "modified passive estimation algorithm", "modified bayesian optimization algorithms", "modified game optimization algorithms", "modified policy optimization algorithms", "modified adaptive optimization algorithms"
"modified parameter optimized algorithmss" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter 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 passive optimization algorithms") OR ("modified parameter optimized algorithmss"))~.
• Removing quotes may allow a broader search: (( modified passive optimization algorithms ) or ( modified parameter optimized algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive optimization algorithms") or ("modified parameter optimized algorithmss"))*.
