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