Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation 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"

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