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