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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimization algorithm") or ("modified seird optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimization algorithm") OR ("modified seird optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) or ( modified seird optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") or ("modified seird optimization algorithmss"))*.
