Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified caging prediction algorithm" » "modified caging predation algorithm", "modified caging predators algorithm", "modified learning prediction algorithm", "modified churn prediction algorithm", "modified cliff 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 optimizer algorithms\") OR (\"modified caging prediction algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimizer algorithms ) OR ( modified caging prediction algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimizer algorithms") OR ("modified caging prediction algorithm"))*.
