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"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified bayesian optimization algorithm") or ("modified passive optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithm") OR ("modified passive optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithm ) or ( modified passive optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithm") or ("modified passive optimization algorithmss"))*.
