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 location optimization algorithm" » "modified location optimization algorithms", "modified location estimation algorithm", "modified location estimation algorithms", "modified allocation optimization algorithm", "modified static optimization algorithm", "modified carbon 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 parameter optimisation algorithm") OR ("modified location optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithm ) or ( modified location optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimisation algorithm") or ("modified location optimization algorithm"))*.
