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