Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"
"modified charging optimized algorithms" » "modified charging optimized algorithm", "modified charging optimizer algorithms", "modified choosing optimizer algorithms", "modified caging optimized algorithms", "modified carbon optimized algorithms"

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

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