Perhaps you should try some spelling variations:
"modified response optimization algorithms" » "modified response optimisation algorithm", "modified response estimation algorithms", "modified response estimation algorithm"
"modified parameters optimisation algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters 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 response optimization algorithms\") OR (\"modified parameters optimisation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified response optimization algorithms ) OR ( modified parameters optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified response optimization algorithms") OR ("modified parameters optimisation algorithms"))*.
