Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified df convolutional algorithm" » "modified df convolution algorithms", "modified df evolution algorithm", "modified df evolutionary algorithm", "modified d convolutional algorithm", "modified deep convolutional algorithm", "modified _ convolutional algorithm", "modified adam convolutional algorithm", "modified bi1 convolutional 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 algorithm") or ("modified df convolutional algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithm") OR ("modified df convolutional algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( modified df convolutional algorithm ))*.
