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

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 parameter optimizer algorithms") or ("modified location optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimizer algorithms") OR ("modified location optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified parameter optimizer algorithms ) or ( modified location optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimizer algorithms") or ("modified location optimisation algorithm"))*.
