Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective estimation algorithm") OR ("modified caging prediction algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective estimation algorithm\") OR (\"modified caging prediction algorithm\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) OR ( modified caging prediction algorithm ))*.
