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