Perhaps you should try some spelling variations:
"modified response optimization algorithm" » "modified response optimization algorithms", "modified response optimisation algorithm", "modified response estimation algorithm"
"modified parameters estimation algorithmss" » "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameter estimation algorithmss", "modified parameter estimates algorithmss", "modified parameter optimization algorithmss"

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 algorithm\") OR (\"modified parameters estimation algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified response optimization algorithm ) OR ( modified parameters estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified response optimization algorithm") OR ("modified parameters estimation algorithmss"))*.
