Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified fire predation algorithm" » "modified fire predators algorithm", "modified fire estimation algorithm", "modified fire prediction algorithm", "modified seird predation algorithm", "modified bi1 predation algorithm", "modified male 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 fire predation algorithm") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified fire predation algorithm ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified fire predation algorithm") or ("modified multiobjective optimization algorithm"))*.
