Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified passive evolution algorithm" » "modified passive solution algorithm", "modified passive evolutionary algorithm", "modified passive convolution algorithms", "modified adaptive 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 algorithm\") OR (\"modified passive evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) OR ( modified passive evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") OR ("modified passive evolution algorithm"))*.
