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 notion estimation algorithmss" » "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimization algorithms", "modified motion estimation algorithmss"

You may be able to get more results by adjusting your search query.

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