Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified df convolution algorithms" » "modified df evolution algorithm", "modified df solution algorithm", "modified d convolutional algorithms", "modified _ convolution algorithms", "modified adam convolution algorithms", "modified bi1 convolution algorithms"

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

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