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