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