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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective predators algorithm") OR ("modified multiobjective allocation algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective predators algorithm ) or ( modified multiobjective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective predators algorithm") or ("modified multiobjective allocation algorithm"))*.
