Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"how learning method algorithm" » "how learning mom algorithm", "how learning methods algorithm", "how graining methods algorithm", "how learning emotion algorithm", "shot learning method algorithm", "when learning method algorithm", "_ learning method 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: (("how learning method algorithm") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( how learning method algorithm ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("how learning method algorithm") or ("modified multiobjective optimization algorithm"))*.
