Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"modified charging optimized algorithms" » "modified charging optimized algorithm", "modified charging optimizer algorithms", "modified charging optimization 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.

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