Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified time convolution algorithms" » "modified time evolution algorithm", "modified time solution algorithm", "modified time evolution algorithms", "modified bi1 convolution algorithms", "modified male convolution algorithms"

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

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