Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimized algorithms") or ("modified fire predation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithms") OR ("modified fire predation algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) or ( modified fire predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") or ("modified fire predation algorithm"))*.
