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