Perhaps you should try some spelling variations:
"modified charging optimisation algorithms" » "modified charging optimisation algorithm", "modified charging optimization algorithms", "modified charging estimation algorithms", "modified staffing optimization algorithms", "modified caging optimisation algorithms", "modified carbon optimisation algorithms"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation 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 objective estimation algorithm") OR ("modified charging optimisation algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective estimation algorithm ) or ( modified charging optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithm") or ("modified charging optimisation algorithms"))*.
