Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified seird optimization algorithm" » "modified seird optimization algorithms", "modified seird optimisation algorithm", "modified seird estimation algorithm", "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 optimized algorithm") OR ("modified seird optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( modified seird optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") or ("modified seird optimization algorithm"))*.
