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"
"mapping learning predation algorithm" » "mapping learning predators algorithm", "mapping learning estimation algorithm", "mapping learning prediction algorithm", "mapping learning emotion algorithm", "machine learning predation algorithm", "enabling learning predation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learning predation algorithm\") OR (\"modified notion optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( mapping learning predation algorithm ) OR ( modified notion optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("mapping learning predation algorithm") OR ("modified notion optimisation algorithm"))*.
