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

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