Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified _ optimization algorithms" » "modified _ optimisation algorithm", "modified _ estimation algorithms", "modified _ estimation algorithm"

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

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