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

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