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