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