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 optimization algorithms" » "modified seird optimisation algorithm", "modified seird estimation algorithms", "modified seird estimation algorithm", "modified stage optimization algorithms", "modified network optimization algorithms", "modified near optimization algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified seird optimization algorithms") OR ("modified multiobjective optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified seird optimization algorithms\") OR (\"modified multiobjective optimized algorithms\"))".
• Removing quotes may allow a broader search: (( modified seird optimization algorithms ) OR ( modified multiobjective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified seird optimization algorithms") OR ("modified multiobjective optimized algorithms"))*.
