Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified notion estimation algorithms", "modified network optimization algorithm"
"modified learning emotion algorithm" » "mobile learning emotion algorithm", "modified caging emotion algorithm", "modified learning evolution algorithm", "modified learning estimation algorithm", "modified learning predation algorithm", "modified 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: (("modified notion optimisation algorithm") OR ("modified learning emotion algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion optimisation algorithm ) or ( modified learning emotion algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimisation algorithm") or ("modified learning emotion algorithm"))*.
