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