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