Perhaps you should try some spelling variations:
"modified parameters optimization algorithmss" » "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss", "modified parameters optimization algorithmsss", "modified parameters optimisation algorithmss", "modified parameters estimation algorithmss"
"modified policy optimization algorithm" » "modified policy optimization algorithms", "modified policy optimisation algorithm", "modified policy estimation algorithm", "modified topology optimization 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 parameters optimization algorithmss") OR ("modified policy optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters optimization algorithmss\") OR (\"modified policy optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified parameters optimization algorithmss ) OR ( modified policy optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithmss") OR ("modified policy optimization algorithm"))*.
