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