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