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