Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "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"

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