Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation 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.

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