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