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