Perhaps you should try some spelling variations:
"modified multiobjective evolution algorithms" » "modified multiobjective evolution algorithm", "modified multiobjective convolution algorithms", "modified multiobjective solution algorithm"
"modified objective predators algorithm" » "modified objective 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 evolution algorithms") or ("modified objective predators algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective evolution algorithms") OR ("modified objective predators algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective evolution algorithms ) or ( modified objective predators algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective evolution algorithms") or ("modified objective predators algorithm"))*.
