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