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 total optimization algorithmss" » "modified total optimization algorithms", "modified total estimation algorithms", "modified total estimation algorithm", "modified global optimization algorithmss", "modified static optimization algorithmss", "modified qoe optimization algorithmss", "modified thermal optimization algorithmss", "modified ti6al4v optimization algorithmss"

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