Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified drug convolution algorithms" » "modified drug evolution algorithm", "modified drug solution algorithm", "modified drug solution algorithms", "modified df convolution algorithms", "modified orca convolution algorithms"

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

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