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