Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"machines learning emotion algorithm" » "machine learning emotion algorithm", "active learning emotion algorithm", "mapping learning emotion algorithm", "machines learning evolution algorithm", "machines learning estimation algorithm", "machines learning predation algorithm", "machines 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: (("modified multiobjective optimized algorithm") OR ("machines learning emotion algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( machines learning emotion algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") or ("machines learning emotion algorithm"))*.
