Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified traces evolution algorithm" » "modified traces solution algorithm", "modified traces evolutionary algorithm", "modified traces convolution algorithms", "modified sales evolution algorithm", "modified time evolution 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 optimizer algorithms") OR ("modified traces evolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimizer algorithms\") OR (\"modified traces evolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimizer algorithms ) OR ( modified traces evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimizer algorithms") OR ("modified traces evolution algorithm"))*.
