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"
"designed network optimisation algorithm" » "designed network optimization algorithms", "designed network estimation algorithm", "designed network estimation algorithms", "designed network optimization algorithm", "defined network optimisation algorithm"

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: (("designed network optimisation algorithm") OR ("modified invasive convolution algorithms"))~.
• Removing quotes may allow a broader search: (( designed network optimisation algorithm ) or ( modified invasive convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimisation algorithm") or ("modified invasive convolution algorithms"))*.
