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 prediction algorithm" » "mobile learning predation algorithm", "mobile learning predators algorithm", "machine learning prediction algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimized algorithm\") OR (\"mobile learning prediction algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) OR ( mobile learning prediction algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") OR ("mobile learning prediction algorithm"))*.
