Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified traces convolutional algorithm" » "modified traces convolution algorithms", "modified traces evolution algorithm", "modified traces evolutionary algorithm", "modified trained convolutional algorithm", "modified graph convolutional algorithm", "modified deep convolutional algorithm"

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