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

Try widening your search to All Fields.

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

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