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