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 evolution algorithms" » "modified time evolution algorithm", "modified time convolution algorithms", "modified time solution algorithm", "modified bi1 evolution algorithms", "modified male evolution 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 time evolution algorithms") OR ("modified multiobjective optimized algorithm"))~.
• Removing quotes may allow a broader search: (( modified time evolution algorithms ) or ( modified multiobjective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified time evolution algorithms") or ("modified multiobjective optimized algorithm"))*.
