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