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