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