Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified based convolution algorithms" » "modified based evolution algorithm", "modified based solution algorithm", "modified dilated convolution algorithms", "modified based continuation algorithms", "modified male convolution algorithms"

Try widening your search to All Fields.

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

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