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