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

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified response optimisation algorithm") OR ("modified parameter optimisation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified response optimisation algorithm ) or ( modified parameter optimisation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified response optimisation algorithm") or ("modified parameter optimisation algorithmss"))*.
