Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified deep evolution algorithm" » "modified deep solution algorithm", "modified deep evolutionary algorithm", "modified deep convolution algorithms", "modified delphi evolution algorithm", "modified df evolution algorithm", "modified near evolution 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 deep evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimizer algorithms") OR ("modified deep evolution algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimizer algorithms ) or ( modified deep evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimizer algorithms") or ("modified deep evolution algorithm"))*.
