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