Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified made evolution algorithm" » "modified made solution algorithm", "modified made evolutionary algorithm", "modified made convolution algorithms", "modified sales evolution algorithm", "modified time evolution algorithm", "modified male evolution algorithm", "modified adam evolution algorithm", "modified df 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 made evolution algorithm") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified made evolution algorithm ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified made evolution algorithm") or ("modified multiobjective optimization algorithm"))*.
