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