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

Try widening your search to All Fields.

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