Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"enabling learning a algorithm" » "mapping learning a algorithm", "enabling learning _ algorithm", "enabling learning _ algorithms", "enabling learning adam algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("enabling learning a algorithm") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( enabling learning a algorithm ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("enabling learning a algorithm") or ("modified multiobjective optimization algorithm"))*.
