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