Perhaps you should try some spelling variations:
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"
"mapping learning emotion algorithm" » "mapping learning evolution algorithm", "mapping learning estimation algorithm", "mapping learning predation algorithm", "machine learning emotion algorithm", "enabling learning emotion algorithm", "mapping learning method algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping learning emotion algorithm") or ("modified objective solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mapping learning emotion algorithm") OR ("modified objective solution algorithm")).
• Removing quotes may allow a broader search: (( mapping learning emotion algorithm ) or ( modified objective solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning emotion algorithm") or ("modified objective solution algorithm"))*.
