Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified changing evolution algorithm" » "modified changing solution algorithm", "modified changing evolutionary algorithm", "modified changing convolution algorithms", "modified caging evolution algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimized algorithms\") OR (\"modified changing evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) OR ( modified changing evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") OR ("modified changing evolution algorithm"))*.
