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