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 optimizer algorithmss" » "modified parameter optimizer algorithms", "modified parameter optimized algorithm", "modified parameter optimization algorithmss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameter optimizer algorithmss") or ("modified multiobjective optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimizer algorithmss") OR ("modified multiobjective optimized algorithms"))*.
• Removing quotes may allow a broader search: (( modified parameter optimizer algorithmss ) or ( modified multiobjective optimized algorithms ))*.
