Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"code learning predation algorithm" » "code learning predators algorithm", "code learning estimation algorithm", "code learning prediction algorithm", "code learning emotion algorithm", "how learning 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 ("code learning predation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithms") OR ("code learning predation algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) or ( code learning predation algorithm ))*.
