Perhaps you should try some spelling variations:
"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"
"modified parameters estimation algorithmss" » "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameter estimation algorithmss", "modified parameter estimates algorithmss", "modified parameter optimization algorithmss"

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 estimation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified location optimization algorithm ) or ( modified parameters estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified location optimization algorithm") or ("modified parameters estimation algorithmss"))*.
