Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified charging evolution algorithm" » "modified charging solution algorithm", "modified charging evolutionary algorithm", "modified charging convolution algorithms", "modified caging evolution algorithm", "modified carbon evolution algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified charging evolution algorithm") OR ("modified multiobjective optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified charging evolution algorithm ) or ( modified multiobjective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging evolution algorithm") or ("modified multiobjective optimized algorithms"))*.
