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