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