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