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