Perhaps you should try some spelling variations:
"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 optimisation algorithm"
"modified caging optimized algorithm" » "modified caging optimized algorithms", "modified caging optimizer algorithms", "modified aging optimized algorithm", "modified changing optimized algorithm", "modified charging optimized algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters estimation algorithms") or ("modified caging optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters estimation algorithms") OR ("modified caging optimized algorithm")).
• Removing quotes may allow a broader search: (( modified parameters estimation algorithms ) or ( modified caging optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithms") or ("modified caging optimized algorithm"))*.
