Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"modified write optimisation algorithmss" » "modified write optimization algorithms", "modified write estimation algorithms", "modified write estimation algorithm", "modified write optimization algorithmsss", "modified write estimation algorithmss", "modified write estimation algorithmsss"

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