Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified up evolution algorithm" » "modified up solution algorithm", "modified up evolutionary algorithm", "modified up convolution algorithms", "modified _ evolution algorithm", "modified co evolution algorithm", "modified up solutions algorithm", "modified df evolution algorithm", "modified bi1 evolution algorithm"

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 multiobjective optimized algorithm") OR ("modified up evolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( modified up evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") or ("modified up evolution algorithm"))*.
