Perhaps you should try some spelling variations:
"modified policy optimization algorithmss" » "modified policy optimization algorithms", "modified policy optimisation algorithm", "modified policy estimation algorithms", "modified policy optimization algorithmsss", "modified policy optimisation algorithmss", "modified policy estimation algorithmss", "modified topology 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 policy optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithm") OR ("modified policy optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithm ) or ( modified policy optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithm") or ("modified policy optimization algorithmss"))*.
