Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"modified seird optimization algorithms" » "modified seird estimation algorithms", "modified seird estimation algorithm", "modified seird optimized algorithms", "modified stage optimization algorithms", "modified network optimization algorithms", "modified near optimization algorithms"

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 seird optimization algorithms") OR ("modified multiobjective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified seird optimization algorithms ) or ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified seird optimization algorithms") or ("modified multiobjective optimisation algorithm"))*.
