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