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