Perhaps you should try some spelling variations:
"modified policy optimisation algorithms" » "modified policy optimization algorithms", "modified policy estimation algorithms", "modified policy estimation algorithm", "modified policy optimization algorithmss", "modified policy estimation algorithmss", "modified topology optimization algorithms"
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified policy optimisation algorithms") OR ("modified parameter optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified policy optimisation algorithms\") OR (\"modified parameter optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified policy optimisation algorithms ) OR ( modified parameter optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified policy optimisation algorithms") OR ("modified parameter optimisation algorithm"))*.
