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 predation algorithm" » "modified learning predators algorithm", "modified learning estimation algorithm", "modified learning prediction algorithm", "modified learning emotion algorithm", "mobile learning predation algorithm", "modified caging predation algorithm"

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

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