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"

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"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"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"))*.
