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