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 solution algorithm" » "modified charging evolution algorithm", "modified charging convolution algorithms", "modified charging evolutionary algorithm", "modified caging solution algorithm", "modified carbon solution algorithm", "modified charging station algorithm"

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

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