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