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