Perhaps you should try some spelling variations:
"enabling learning evolutionary algorithm" » "enabling learning evolution algorithm", "enabling learning solution algorithm", "mapping learning evolutionary algorithm"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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 evolutionary algorithm") OR ("modified objective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( enabling learning evolutionary algorithm ) or ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("enabling learning evolutionary algorithm") or ("modified objective optimisation algorithm"))*.
