Perhaps you should try some spelling variations:
"modified aging optimisation algorithm" » "modified aging optimization algorithms", "modified aging estimation algorithm", "modified staffing optimization algorithm", "modified caging optimisation algorithm"
"modified bayesian estimation algorithms" » "modified bayesian estimation algorithm", "modified bayesian optimization algorithms", "modified bayesian approximation algorithms"

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 estimation algorithms\") OR (\"modified aging optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified bayesian estimation algorithms ) OR ( modified aging optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian estimation algorithms") OR ("modified aging optimisation algorithm"))*.
