Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified arcad predators algorithm" » "modified arcad predation algorithm", "modified marine predators algorithm", "modified orca predators algorithm", "modified adam predators algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

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