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