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 _ optimisation algorithm" » "modified _ optimization algorithms", "modified _ estimation algorithm", "modified _ estimation algorithms"

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