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