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

Try widening your search to All Fields.

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