Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified parameter optimized algorithmss" » "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimized algorithms", "modified parameter optimizer algorithmss", "modified parameter optimization algorithmss"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimized algorithms\") OR (\"modified parameter optimized algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) OR ( modified parameter optimized algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") OR ("modified parameter optimized algorithmss"))*.
