Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimisation algorithms", "modified parameters estimation algorithmss"
"modified location optimization algorithm" » "modified location optimisation algorithm", "modified location estimation algorithm", "modified location estimation algorithms", "modified allocation optimization algorithm", "modified static optimization algorithm", "modified carbon optimization algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters optimization algorithms") or ("modified location optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithms") OR ("modified location optimization algorithm")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) or ( modified location optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithms") or ("modified location optimization algorithm"))*.
