Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified orca evolutionary algorithm") OR ("modified multiobjective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified orca evolutionary algorithm\") OR (\"modified multiobjective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified orca evolutionary algorithm ) OR ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified orca evolutionary algorithm") OR ("modified multiobjective optimization algorithms"))*.
