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 objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified policy optimization algorithmss\") OR (\"modified objective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified policy optimization algorithmss ) OR ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified policy optimization algorithmss") OR ("modified objective optimization algorithm"))*.
