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