Perhaps you should try some spelling variations:
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"mobile learning solution algorithm" » "mobile learning evolution algorithm", "mobile learning convolution algorithms", "mobile learning evolutionary algorithm", "mobile learning convolution algorithm", "mobile learning emotion algorithm", "machine learning solution 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 solution algorithm\") OR (\"modified parameters optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( mobile learning solution algorithm ) OR ( modified parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("mobile learning solution algorithm") OR ("modified parameters optimisation algorithm"))*.
