Perhaps you should try some spelling variations:
"modified multiobjective allocation algorithm" » "modified objective allocation algorithm", "modified multiobjective estimation algorithm", "modified multiobjective evolution algorithm", "modified multiobjective predation algorithm"
"modified objective predators algorithm" » "modified objective predation 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 allocation algorithm\") OR (\"modified objective predators algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective allocation algorithm ) OR ( modified objective predators algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective allocation algorithm") OR ("modified objective predators algorithm"))*.
