Perhaps you should try some spelling variations:
"modified parameters optimisation algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimization algorithms", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithmss", "modified parameters estimation algorithmss"
"modified location optimisation algorithm" » "modified location optimization algorithms", "modified location estimation algorithm", "modified location estimation algorithms", "modified allocation optimization algorithm", "modified carbon optimisation 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 optimisation algorithms") or ("modified location optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimisation algorithms") OR ("modified location optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified parameters optimisation algorithms ) or ( modified location optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimisation algorithms") or ("modified location optimisation algorithm"))*.
